Valve is already evil: they locked down their steam client (unacceptable in the times of GOG, and Epic Games) and allow developers to put DRM in their games. Outside of that they were the pioneers of digital gambling with CS:GO and TF2 and using anti-features as a way to entice people to purchase micro-transactions.
Bottles as flatpak is an amazing way to run windows dependent software isolated from your main system. Flatpak will automatically bundle Wine and 32 bit library runtimes and bottles packages in DXVK (no need to enable multilib). If you use ProtonUPQT you can even get the bleeding edge GE wine as a runner for your programs in bottles.
I pirate because Steam is a garbage program for playing games and Valve is an evil company. So I pay for games in Steam but will just pirate a Non DRM-Non steam affiliated copy of the game to backup on my own local storage.
