I am very aware of it, and I've read the proposal.

This is absolutely not what’s being demanded.

It is 100% what is being demanded, the proposal says:

This practice deprives European citizens of their property by making it so that they lose access to their product an indeterminate/arbitrary amount of time after the point of sale. We wish to see this remedied, at the core of this Initiative.

The ONLY way to do this is everything aformentioned. It's indirect in how it's asking for it, but in real life practice the only way the proposal actually gets what it wants, is by either:

A: Demanding (foolishly) that the game devs keep the servers up and running (not happening, get over it)

B: Demanding (even more foolishly) that the game devs release a copy of all the necessary backend technology for self hosting, which you can't demand because it's proprietary and some of it may still be in use, so it's a security and business risk to expose that sort of stuff, so no business will ever be able to feasibly do that.

Sorry but no, it's a foolish demand.
