Lol. Always suspected there was a scam there, but every time I bring it up in a conversation - people just call me a conspiracy theorist.
This goes for pretty much everything though. Planned obsolescence is real, but people think it's just the natural way of things.
DLCs: Games are expected to have DLCs nowadays, so game devs purposefully hold back some ideas for potential DLCs, often crippling the main game as a result.
Subscription services: For pretty much anything, but especially those automated monthly payments, which you won't bother cancelling, even if you feel like you're not using the service to its fullest.
