Indeed, although that is mostly just a right to keep your game in a functional state after you getting sold a license to use it with no specified end of service date.

In other words (for the people who don't know, and there has been misinformation spread by some people with quite a bit of social clout):
"We can terminate your game at any point in time for any reason." in EULAs is to be removed, and instead, publishers/developers need to either specify that their product license is only good for a specified timeframe (to make it more like a rental or something, or a true subscription like world of warcraft).

Or, if the license stays open ended, then, at the time of shutting down a game, they have to release binaries or other ways to keep in a state of 'reasonable playability', not even FULL playability.

It's also not retroactive, so any MMO or whatever that might be fearing that they need to do something radical is not warranted, it would only be after the passing of the new laws, and it wouldn't even need to be 100% exact the same playability.
Like, If they don't want to release a private server software, then they should deliver a patch that makes it possible to still play the game alone, even if it's not 100% feasible or balanced around it.

It just has to do something that isn't NOTHING, aka 'death', but also more than just a token gesture, it should be 'reasonable'.

And as far as I know ,that is the only vague demand the movement has, and it's rooted in benevolence toward the game makers/publishers, were it more exact then it would be something like:
Game needs to be 1:1 100% playable after shutdown with all the material provided to the customer to continue the experience he or she paid for.

But do they still sell towers? I haven't seen one in a shop window for years.

Never been to UK so I don't know what they sell over there.
But yeah, some hardware companies are still selling them, brand new, and you can even choose pre-built tower or empty tower case.
For example Alienware is the most expensive case I've ever seen over here, but there are still plenty others to choose from.
Thing with standard metal PC case is that nothing ever breaks, I haven't replaced my case in ~20 years. That's why you don't see them advertised much.
It needs regular cleaning, maybe some new fans every once in a while and that's it. Laptop needs all that, plus batteries, plus it's much harder to change thermal paste.

Also, if you spill liquid on your desktop keyboard you simply clean or replace the keyboard.
Spill something on your laptop and you can pick 5 internal components you might need to replace, which is more expensive than a new laptop.

Hi,
I still have a couple of towers that I moved from Illinois. Most reliant on my numerous Laptops and some of my <embedded> systems for different functions. I have limited space here in Florida. I moved from the Farm (5000 sq ft) to town (3000 Sq ft) and to Florida (1900 sq ft) so my downsizing from the Farm to Florida was rather large. I sold all my Electronic Shop and my work working shop as I couldn't see purchasing more property to have everything.

I did leave a lot of clients in Illinois but gave good references for additional help. I really do not miss the hassle with clients as most thought they owned you and insisted their problem was an emergency and had to be attended too immediately. Now I have a true leisure life here in Florida and enjoy it every day!

As to my towers, I'm thinking to bring things back to life to have something to fill my days since it rather hot humid days now in Florida.
I no longer have the means to design and build my interfaces nor really interested in doing that anymore. But I do like to tinker still and things are getting exciting with all the new hardware out there.

It would be nice to have computer printers where you just poured the ink in, like filling a car.

Then get one. Inkjets with tanks have been around for over a decade now.

What brands or models allow this please?

Epson have them for a start.

Search Ink Tank printers - much more economical than Ink Jet
