Most likely your software will work via bottles or wine
No, for the examples above it will not. Quite a lot of professional software will not run under wine (and a lot of hobbyists use professional software) - games work particularly well because they mostly do their own thing and depend less on Windows-specific APIs. And if you use a VM via Winboat then you’re just using Windows in the background, which is a workaround, but kinda defeats OP’s argument that there’s “no difference”.
To be clear: I’m daily driving Linux and I’ve not booted into Windows for more than a year. But it’s just wrong to say that they are on par with each other for a lot of usecases.









I’m not a lawyer, but I would argue this actually means that even people who get it from Gumroad can’t use it “legally”. There should be a license which expresses your intent.
