alt Hacker NewsForking is fine, do whatever, but as soon as you make actual changes to the code then adopt your own name. This is what trademarks are for, it's just that official trademark registration is somewhat inaccessible (eg: cost) for open source projects. Could you imagine trademarking every little project you make just in-case it gets repackaged by someone who tears huge chunks of it out?
As it turns out, trademarks for small open-source projects are effectively worthless (https://news.ycombinator.com/item?id=44883634), so there's effectively no real solution to people appropriating your project's name while repackaging their inferior fork of it.
