Many cracks rely on underlying mechanisms of Windows that end users don’t really need to think about. So if “better for piracy” is purely about ease of applying cracks and successfully executing them, Windows is definitely better. That doesn’t mean it offers the best possible experience though.
Any old-school cracks (anything that isn’t a hypervisor bypass for games with denuvo, which isn’t recommended for most users anyway) will run on Linux, with varying levels of required tinkering. A lot of the time you can just add a cracked game or app to steam and run it there, but sometimes it isn’t quite that simple. It depends entirely on the game/app and how the crack functions.
If you’re willing to learn the tinkering part, it’s good knowledge to have and gives you more flexibility over how software/games are run. This is particularly useful for mid-tier machines that can’t max out all settings on all games, for example with forcing specific resolutions, display modes, virtual displays, upscaler presets, global upscaling, gamepad config.
Given there are very few roadblocks with Linux I don’t think there is an OS that is “best for piracy”, rather the best choice depends on user preferences and expectations. Certainly if your top priority is the least amount of effort to get things running, choose Windows. But you’d also need to accept dealing with Microsoft’s bullshit, and forego performance improvements you’d potentially get with Linux.
It’s only quite recently that some countries have begun to start trading oil in yuan. It’s certainly not easy to circumvent the petrodollar system that’s been in place since WW2. For one thing, the US will start bombing you.
