I was the first to return markdown and use reader mode stuff to strip irrelevant stuff. Theres copying and there's talking to the founder sounding interested to have your team copy what I did in the background. One is fair game, the other is a dick head move.
I think that is a neat idea and it sucks this happened, but how long before somebody simply saw that feature and replicated it? I'm curious, had you considered a deeper moat than that?
This is especially relevant given AI is making this kind of thing easy at an industrial scale. I think we should all be looking for alternative moats.
Not sure about the first claim. But yes, talking to the founder, sharing details and having it stolen is not a good look. Sorry that happened to you.
