You don't understand because most would-be converts by far want a free-as-in-beer Windows or Mac.
Annoyed by Microsoft 365 nagging? Sick of the Apple ecosystem? Mah freedom? Nevermind all that, they're just excuses. The real reason is they don't want to pay $200+ for a Windows license or $1000+ for a Mac.
Sure, I understand the "I don't want to pay" intention. What I don't get is why anyone would work for free to convert those people. I don't need them to use Linux, and in fact I don't want them here because they will push Linux towards a direction I don't like.
