Funny, I've never once in all my days installed malware from a Linux package manager, and this "seal of approval" doesn't cost me or the developer any money at all.
That’s because your computer is a hobby, and mine is a business. My customers use Windows and macOS. They have happily paid for my house, my car and my retirement. :o)
If you want to justify rent-seeking because it helps you pay for your lifestyle, come out and say so in the first place instead of pretending it's for the benefit of your users. But claiming that Linux is a "hobby" on HN is essentially trolling.
