Or more likely IT asked for IDS, DR, security audits etc etc and that budget got nixed as costing too much

Easy easy

Xfs, ext4 - lack data integrity checking, no mash up of layers with stratis please.
Btrfs - no tiered storage

Bcachefs does raid 5/6 with no write hole.

Btrfs never seems to fix fundamental issues like raid 5.

Yes a very dark day for Linux. It so badly needs a NG filesystem.

Have the famous Linux kernel lead and the NT/XP/Win server kernel lead ever met.. ?

Pretty sure Cutler used to have some harsh wordscabout Unix in the past

Yup.
I used to run RHEL at work, Centos at home and Fedora on Desktop (work and home)
I used to send bug reports to Fedora in the hope they would make it to RH and Centos later.
Now why should I help you improve RHEL when you are effectively calling me a thief.

Sorry as a long long term user and large customer of RHEL I just hate what RH has done here.
As a RHEL customer I used to benefit from Centos later Rocky/Alma, FAQs, bug reports, HOWTO and most importantly third pary repos built with these (and by these people). RHEL is pretty useless without these (certbot, ffmpeg, VLC etc etc).

This makes RHEL so much less useful. And I would always test on Centos and deploy on RHEL (with full subscriptions).

I used to be happy to take the latest Fedora and test and report bugs, knowing it would improve my work RHEL and my home Centos/Rocky setup too. Great symbiotic relationship, sorry that's all gone now. Why should I do anything for Fedora or RHEL. Thanks for the leech comment to customers !

I'm reinstalling my home stuff with Debian now and gaining more experience with that (I haven't run Debian in decades).

I doubt RH is independent of IBM, big companies can't help themselves, but worse the IBM influence may be as simple as "RH you need to increase revnue by xyz and increase sub by etc" and RH looks for a radical (read nasty quick hack) to achieve this.

It's so disingenuous to say RH wasn't making money from RHEL, they made increasing profits year on year, and still are.

I think RH might have "pissed on their chips" now. RHEL is a lot less useful without the re-builders and I speak as someone who used to recommend RHEL and had a large contract with them whilst at a previous employer. Without the rebuilders there will be a lot less testers/bug reports/workarounds found, less 3rd party ISVs being interested in RHEL software as you just shrank the installed base, less HowTo's usually written by re-builder users, less easy to test RHEL using Alma/Rocky before going into production on RHEL. Worst of all perhaps, less third party repo software usually built by people using Alma/Rocky, making RHEL much much more of a pain to use (certbot, VLC, ffmpeg, etc etc), now I have to build all this stuff myself, great.

I feel no desire now to help RH improve Fedora, I used to always test the latest releases and reported bugs back, in the hope RHEL would be better when it came out.

I'm testing Debian now!

Maybe not a big deal for most but having IPv6 shows a commitment to the future.
Also streaming with CGNAT it would seem streaming with IPv6 would be more sensible.

Go and understand sampling theory before spouting this rubbish

Very almost. It's still guided by Google. For example there is no way of hosting your own sync server (for syncing Bookmarks, Open tabs, history and passwords etc). People have added bug reports but have been told it just won't happen.It's very clear vendor lock-in.

People always say don't use guest WiFi. This isn't 2010, what service are you using on your smartphone/laptop that isn't SSL? Should be fine now.

Well isn't Teams just an "Electron" app, which means it's just a web browser frame with webcontent on all platforms?

On Linux, Teams is just an Edge frame like any other. Also though, Linux Teams has some less functionality (see the very long running request from Linux users on Teams insiders) than Windows Teams, so therefore you would assume Windows Edge has greater functionality than Linux Edge. Have they addressed this?

Coming soon(ish) Outlook is also going to be an "Electron" app, so just a web browswer with webcontent, so will likely be cross platform.

Worse still when MS gained market share over Netscape, they just dumped it with zero warning.
