Gorge Bucaran, author of Colorette, summarizes your actions here https://github.com/ai/nanocolors/pull/14#issuecomment-927134...:
"Colorette isn't some obscure project either. It is well used. Now imagine I find a project that meets that description. Clone it. Erase the .git directory. Initialize a new repository. Make a few extraneous changes. Incorrectly benchmark it. Falsely claim improved performance. Tweak the docs. Change the name. Add a logo. Start aggressively promoting it and sending PRs to high-profile projects while leveraging a non-trivial social media following. I'm not against forking a project and adding new value to it. I encourage that. But that's not what's going on here. This is the collector getting away with a new piece for their collection."
Comparing that, to "promoting alternatives" to one of your projects on Twitter, shows a creepy lack of acknowledgement.
But that's why we're here, isn't it?
