"You make it sound as if I have a right to the content other people produce. I don't and never did. I don't consider it to be "culture" either."
No, but you should have a right to play content you've paid for on a device of your choosing without artificial restrictions.
...unless you have agreed to those restrictions when you paid for the content.
Which is really the problem. If the content creators can choose what you play content you've paid for on, especially from the web, then they can arbitrarily prevent it working on your old device, and force you to buy a new device when there's nothing wrong with your old one. They can work with companies like Microsoft to ensure it only works on Microsoft devices for example and kill viewing of content on iOS and Android dead in the water.
You seem to think it's just about viewing content illegally, it's not. It's about having control of content you have obtained legally and not allowing content to be used as a tool to be used by vendors in other markets such as hardware to gain advantages through artificial incompatibility and planned obsolescence.
If content producers want us to rent content only then they need to lower their prices to reflect that and make it clear. Right now they want to pretend you're purchasing content to keep whilst only giving you rental rights. This is unacceptable.
If you don't agree to the conditions they place on your having access to their content, then choose not to view/listen to it. The choice it fully yours - you are not forced to agree to onerous conditions. You choose to willingly because you want the content they are providing.
The dream of content companies is that they can use DRM to force you to rebuy content every single time you buy a new device. They view this as a way of increasing profits without doing any additional work by profiting off the same thing over and over. They're trying to turn a purchased product into a throwaway consumable that you have to replace with each device using artificial means without dropping the price to match. That is not acceptable.
Then don't accept it by not giving money to such companies. The choice is easy: pay them money and abide by their conditions, or don't.
The internet and digital revolution has made content far cheaper to reproduce and deliver so in a healthy natural market the price for consumers should come down. Content producers want to use DRM to subvert that and instead make the cost of content in the digital age go up by making you buy it over and over if you want to keep watching it. This is their ultimate dream and their preferred goal with DRM as it allows massive company growth for zero effort if it's ever achieved.
If no-one bought such content then these companies would have to change their ways. There must be a market for content with these strict conditions on it, because they continue to operate this way. As I said, no one is forcing your to partake in such content. Vote with your wallet.
