> I said "a decent chance that's as good as buying the thing".
I didn't think I would need to quote more of your message, its essence is that you think these kinds of licenses *can be* "as good as buying" when they demonstrably have never been close to it... and it's by design.
> If these mega companies stick around and continue to offer access to the content, then it is as good as buying it (arguably better if you don't have to store it and can download onto many devices over decades)
But the really don't, they regularly cut access to content they pretend to have "sold" to you with a "buy" button. They have redefined the words "buy" and "purchase" to match an old model of sales where you actually had an irrevocable access to the content. All this law says is that it should be made clear to the end user.
Currently companies hide this to customers in pages-long EULAs and behind misleading "Buy" buttons. It shouldn't be so hard to be honest about their business model... unless maybe they think people would reconsider "buying" all these things if they knew they can be taken away from them so easily, without refunds, often without even warning them.
> or loses access to the relevant rights.
In most cases the companies don't "lose" anything, they decide that continuing to pay the copyright holders for this content is not profitable for them anymore (or fail to negotiate it within their acceptable margins), so they stop paying, and remove the content from their catalog. Without any regard, consultation, or compensation for the customers who paid to access it.
> If you can move the content from a PS5 to a PS6 in 5 years, then arguably it's fine to say you "bought" it. But if they're wiping the content from your local devices, then you've definitely not bought the thing.
Many of these services stream the content to you on-demand and don't even allow local copies... or if they do, they gate the local copy behind online renewable keys limited in time. Sony does this by forcing you to connect your console every few days if you want to be able to continue to play "offline".
And to be honest Sony's case is interesting but not very significant, both Amazon and Apple have been caught removing content (removed books from Kindle, removed songs/albums from iTunes, if my memory serves me well, you can easily google the cases), they got class action lawsuits against them and both settled. More than once. They settle because they know their customers expectation of "buying" is not the one their EULAs guarantees, and they really don't want courts to rule on these EULAs or whether "Buy" is a misleading term. That's why lawmakers have to do it. It's really not a matter up for discussion that these companies will remove content sooner or later, the OP demonstrates so, the previous settled cases too... so unless you provide a framework in which these companies can offer an access that is actually as good as actually buying a physical media, it's just wishful thinking to believe they "can" do it, there is literally no incentive for them to do it and they've designed the current business model this way on purpose, removing all control from their customers.
