Even with a steam deck, I am probably going to get the Switch2, mostly because I can lower my head on in-game profiteering, which is increasingly prevalent on steam games.
The Store UI is disgusting and intrusive compared to all other competitors who actually have a decent overview and design..
You can collect gems, cards and other misleading virtual currencies.. Tons of misleading business practises and time-consuming bloatware distractions hidden behind that terrible UI.
Steam is first and foremost DRM. A game-prison. You don't own a single thing. Gamers have totally drunk the kool aid.. They forgot back when Steam was bloatware forced on Half-Life and Valve games and it was despised for a decade before they became complacent little worshippers.
