The new model makes no sense whatsoever.

If I install a game I bought on both my desktop and steamdeck, the devs have to pay unity twice. If I uninstall it and re-install it, they have to pay it thrice. Four times if I ever use my laptop to play.

If I share the game with my dad and sister via steam family share, the devs have to pay yet another two times.

But I only paid for the game once.

It's complete insanity. Do they have to pay again for every update, does that count as a new install? What about games on subscription services?
