Is Brave not open source?
I mean I get why a normie would back down even from a bullshit suit from a company (laws favor capital and they can drag it forever to fuck you… Nintendo loves doing this too with the Switch modding community (most recently))
Assholes either way. Developing using open source code and then crying foul when someone removes you bullshit.
This is their repository btw: github.com/BoldBrowser
It seems they moved to making Ungoogled Chromium after that (you can see that Eloston, the major dev of that Chromium fork, contributed to the repo) and then maybe they just changed the repository and continued working elsewhere? That would at least explain the README.
