The point is not about ideological debates, making money from GPL software is purely a practical business decision. Many people are doing it, see e.g. https://reacher.email/ (written in Rust btw). Source: 11 months ago
I run an open-source [1] email verification API, called Reacher. I managed to hit 10k ARR this year (1st year). It's written in Rust, self-hostable, and does not use a DB of emails (like some competitors do). Landing page: https://reacher.email.

On your site (https://reacher.email) it shows "Open-Source" next to the MIT logo. To any reasonable person, that means "it's licensed under the MIT license". Instead, it's licensed under the AGPL. It would be good if you changed it to remove the implication that it was MIT licensed. - Source: Hacker News / almost 3 years ago
This feels like a service that would be used by shoddy email marketers and spammers to reduce the number of bad emails they send, so that they can avoid being blocked. Their home page (https://reacher.email/) mentions lists uses like cleaning "large lists", which comes off to me as code for "send mail of dubious quality without tripping alarms". - Source: Hacker News / almost 3 years ago
