If it is "trivially verifiable" then you should be able to provide examples. Some anti cheat tools, such as "Easy Anti Cheat" are supported on Steam Deck, some are not supported yet. Perhaps some will never be supported. AFAIK these later categories are generally due to anti cheat hooking into low level windows functionality that Proton doesn't support. You could argue this is "blocking open software" but that would be a stretch since this behavior is generally better described as a lack of support rather than explicit blocking None of it is due to game publishers including code that limits the hardware that windows runs on (blocking open hardware).
