SteamOS is Google Play Services for desktop linux. For a while you couldn't use the touchpads without running the steam client. They break existing dual boot setups every firmware update so in some ways are more hostile to alternative OSes than Windows. The hardware of Steam Deck is generally more open though if you forgo SteamOS itself.
