It's not an assumption that transitioning to (Proton on) Linux is hard with no prior knowledge.
The Proton thing was just an example. You do not know OP's circumstances. What if they were already tech-savvy?
OP doesn't owe you a question
And I don't owe OP an answer either.
Open Source software for Windows exists therefore it can be installed.
Just because something exists doesn't mean if should be installed. The question isn't about whether or not it can be installed. That's not the point at all.
