Probably not. Although I can’t buy a Steam Deck in my country, Linux is my daily driver on my gaming PC. In my experience, buying games on steam is genuinely much much easier than piracy on Linux. Even just trying to run Windows games purchased elsewhere (such as GOG) to run in wine is much more difficult than steam. There are no other game stores that are anywhere near as good on Linux.

I don’t think it is blocked, just down at the moment.
