Developers of iOS native apps have to know what TLS is because the App Transport Security policy of iOS requires all web APIs used by the application and controlled by its developer to use TLS since 2015.

Indeed. I'm guessing it has some features like QR code reading and Bluetooth beacons for navigation around the airport.

Those aren't the worrying ones though, because you can refuse them. It's the mandatory ones that are the big problem.

Until they see a trailer for a game that looks interesting, click through to learn more about the game, and find that it's available for (say) Linux, Windows, and NES. A lot of games from smaller studios get released on PC first, or PC plus an unlicensed release on a long-obsolete console, while the studio awaits approval to obtain a devkit for the major modern consoles.

Does this include things like Steam Deck?

If you refer solely to physical distribution through big-box electronics store chains in the United States, what's so special about that sales channel?

Likewise, a lot of people use obsolete Mac computers, and a lot of people (including myself) use obsolete Nintendo Entertainment System consoles.

As I understand it, the "obsolete" label applies to a video game console once its manufacturer is no longer certifying new games for it. For example, Shakedown: Hawaii is the last Wii disc game in Europe, the last Wii U disc game in North America, and the last PlayStation 3 game. See list of last licensed games by console.

You are technically correct that the Americans with Disabilities Act 1990 does not apply because Ryanair operates in Europe, not the United States. However, the United States is by far not the only country with a disability discrimination law. Ryanair is headquartered in a suburb of Dublin, Ireland, a European Union member state that has its own disability accommodation law framework. So let me address the spirit of coats's question:

Say someone can't use a smartphone without setting it to use large print. If Ryanair requires its customers to use an application that is incompatible with large print setting, what recourse does the customer have under Irish law?

What country? I seem to remember some countries have instituted policies that require "social" web applications to thoroughly verify the age of all users. Australia, for example, passed such a law that takes effect next month.

One alternative to YouTube is uploading your "shitty but fun songs" on your own website.

How so, now that almost all web and native applications use TLS to communicate with the server? An attacker running a packet sniffer on a TLS session can see the connection's IP address, the server's hostname, the size of communication, and nothing else. This would amount to "A user connected to Ryanair and received a data volume typical of a checkin."

This is the case for many applications. Both major smartphone operating systems' included web browsers support progressive web applications (PWA). These use a service worker, a script cached on the device that acts as a proxy to cache a particular site's pages, scripts, and data and present them to the user even while the device is offline. They grant additional permissions to bookmarks on the device's home screen. For example, Safari for iOS allows a website added to the home screen to use the Push API to receive notifications through its service worker.

However, a lot of service providers maintain a native application for iOS and a native application for Android instead of relying on a PWA. Based on my recent conversation with UnknowingFool, this includes at least Grab, Doordash, Uber Eats, Instacart, Favor, Grubhub, and Postmates, and these providers are thought to have (unstated) good reasons for doing so.

When you buy your ticket, you can just specify that you're disabled and that you need a paper ticket as a special accomodation. After all, they already have these questions for people who need other accomodations (for wheelchairs or food). It shouldn't be too hard to add one more to the list.

And for the passengers that don't have the foresight to check that box when they buy the ticket, I'll bet Ryan Air will be more than happy to supply a paper ticket for an extra $75 fee per boarding pass (or per leg of the journey).

Google Play lists all the permissions:

Device & app history
        retrieve running apps

Location
        approximate location (network-based)
        precise location (GPS and network-based)

Phone
        read phone status and identity

Photos / Media / Files
        read the contents of your USB storage
        modify or delete the contents of your USB storage

Storage
        read the contents of your USB storage
        modify or delete the contents of your USB storage

Camera
        take pictures and videos

Wi-Fi connection information
        view Wi-Fi connections

Device ID & call information
        read phone status and identity

Other
        receive data from Internet
        view network connections
        pair with Bluetooth devices
        access Bluetooth settings
        connect and disconnect from Wi-Fi
        full network access
        control Near-Field Communication
        run at startup
        reorder running apps
        control vibration
        prevent device from sleeping
        read Google service configuration

You can refuse some of those permissions, but it's still a hell of a lot.

That's the key point that people always forget, or simply don't know. Most Chinese people are happy with how things are going. Life is getting better every year. They feel like they are involved in local decisions, and that the government is looking out for them.

I asked a guy about all the CCTV cameras on roads. I noticed them because, unlike the ones in the UK that are hidden and quietly record number plates in a central police database all over the country, the ones in China have a flash so you can't miss them. As well as the licence plate, they get a photo of the driver, hence the need for the flash. I was a bit alarmed, but he said they keep everyone safe and help the police catch criminals. Exactly the same justification used in the UK, only with better PR.

I do 99% of my coding in C these days. I used to do some C# stuff, but it's been a while.

So for me a decent IDE is very very helpful.

That was my other thought, why don't they submit a patch fixing it? Or maybe they did and it just needed review.

Ryanair have two motivations here.

1. Steal your private data, spam you with notifications, the usual app stuff.
2. Make more people pay the check-in fee.

They are always up to stuff like this. The other very common one is rejecting bags that are within their size limits. They have special devices that the bag must fit in, but the dimensions are not the same as the ones in their Terms & Conditions. The device has rounded corners that reduce the volume a little, for example.
