For those who do want to maxprice your product and jack your customers, at least don't go saying you care about the startup community. Actions speak louder than words.
The one that he got off of HN publicity, by posting useful information on his site to share with other people?
That was a very interesting project, so I signed up for updates. Not long after that, his e-mails started being mostly about selling ConvertKit to us, interspersed with useful(-looking?) articles. I can't help but feel like selling ConvertKit was his goal right from the start, and that the web app challenge was just a ruse to get us to receive his sales pitches. This is very clever, of course, but it's sleazy too.
The whole point of signing up for the list is to see how he does what he says he's going to do. The emails are showing you almost EXACTLY what to do if you want to copy him. Would you prefer he put you on his list, then never mention the actual thing he's building?!
Could you try any harder to find something to complain about?
