Is that better? Then you're forcing people to buy an adapter for a controller that is technically natively supported on the console, but simply due to forced obsolesence can't be used on PS5 games.
Outside of simple capitalist "we are a business, and we wan't more money" reasoning, there is no justification for this decision, and it's ridiculous to see so many Sony fans on this forum of all places defending it. That's how it worked in previous generations? That's nice. It's now 2020, your chief competitor is offering compatibility, and you yourself are making the DS4 natively compatible with certain games.
There are no new buttons on the PS5 controller, and there's no reason the DS4 couldn't be supported - except a) Sony trying to push devs to use the new features, and b) you want people to buy new controllers.
When in doubt, assume bad faith on the part of your interlocutors so you can both sides the thing away.
Yeah, people expressing deep concerns that the thread title might be too harsh... on Sony... was definitely a plot twist I didn't anticipate.
But I used the right hashtag on Twitter! And I signalled my moral disapproval in the strongest terms imaginable on a forum! What more do you want?!
