While the page decryption trick should work in Wine just fine (ZeroIT Lab Theia does that too, right?), I don’t remember if Wine provides workingset info like Windows.
EDIT It looks like the Roblox anti-cheat devs themselves explained why Wine was blocked:

Even then it's just a fancy party trick, you can suspend the process call the decryption function enumerating all the pages and take a full dump to get the binary
FYI; Theia is a very bad product. It absolutely tanks binary performance and does little to prevent a moderately competent engineer from cheating in your game.
