This is highly unethical on their part if true, and it seems the reset the entire history of the repository. Could have just forked you. Another hit to the open source community unfortunately

Seriously, if the allegations are real, this is really serious and needs more visibility!

The fact that this post has so little traction here compared to reddit is a bit concerning. Y-Combinator should boot the other startup and bring on the original dev in their place, or at least offer to bring them into a cohort. That would be proper justice while also successfully promoting good culture and dissuading stealing attribution. If not that, then the original dev should be invited to be part of the team with a proper equity share.

That's just the opinion and perspective of another startup founder. We identify our own opportunities and develop our own innovations instead of stealing them. We give credit where credit is due without having to be asked to. I want to crush the culture of stealing other people's ideas. It's been around for a long time but it's really not sustainable. What happens when creatives no longer share openly? Where will the ideas to steal be?
