Not everyone from the remaining checks everything they buy for DRM.
Not everyone from the remaining realize the implications this may have on legit users (backups, conservation...)
Not everyone from the remaining is aware of the technicalities enough to know those technologies may be implemented in the CPU hardware and be revoked at a later time.
Not everyone from the remaining consider DRM to be a bad trade-off, no matter what we think about it, and our as well as their reasons for believing so.
Who are you to take all these, which is a huge part of those that have a possibility to pay those technologies, and call them all "idiot consumers"?
There are probably other areas you don't even realize exist, where to some guy, you are the idiot consumer that is the reason of a huge industry-wide issue still existing.
Outside of technical forums and tech-savvy friends, the only times I hear about DRMs is about video games. And it created reactions. Steam DRMs are easy to bypass, only a minority of games are using Denuvo, nearly no protections ask for kernel-level modules. Online does often rely on central server which is a shame, but most are still unaware the editor will close them one day, and we can hope for an outcry.
Is the real problem (putting aside the ones creating those devices or designing them) really the "stupid consumer" whose lack of knowledge of a subject is being abused to lock him, when no one is there in the circles they are in to educate them?
