DRM when used in a responsible manner is fine. Wanting to protect your work from piracy isn't asking much as a dev.
Any kill switch on content you've purchased isn't fine. Its a kill switch that you don't control, while you have a perpetual right to a license. Why is it there? It harms the paying customer, not the one that doesn't pay. Basically you're treating every paying customer like a potential criminal. This criminalization by design is really the total absence of trust. It only inspires us to be less trustworthy. Its a path of escalation, not de-escalation. The idea is 'if we can lock everything down, we're in control'. Its an illusion, and it leads to bitter and resentful societies. We shouldn't applaud this because of a short term gain perspective from developer side. Neither should you. It damages you too.
Not a single industry has ever really gone down the shitter because of piracy. It just doesn't work like that and it never will.
Music on disc never had it. Why? We copied that left and right. Analog music same.
Digital music, same thing.
Video, same thing.
Its being done because it is technically possible, not because its ethically sound. No amount of DRM fixes shitty game sales numbers either, and there is literally not ONE documented case of a great game not getting the profits it needed to pay for itself (and profit off it) due to lack of DRM. There are just emotions. Lots of emotions, regarding piracy, which is seen as theft by some, and a simple copy by others, while it is both, and at the same time its not. Piracy is really just a niche, but its given way too much attention because profit maximization and commerce has no morals whatsoever. The immorality isn't with pirates, its with corporate.
Look at Larian and Baldurs Gate 3. Probably the GOTY of 2023, no DRM. Only shitty games need DRM, because they're actually not worth their money but people still want to take a look. This echoes in the type of games that are heavy on DRM: its all big publisher work, selling their product not on the merit of it, but of all the nonsense around it. The similarity between lack of innovation and DRM is there too. Indie and DRM... pretty much nonexistant, apart from Steam's very soft DRM, unless there's a gog release as well (which happens a lot).
