Thanks for the credits (creator of React Flow here)! Our website is MIT and so are the docs and all the content but I don't get that you just copied content like whole sentences of the docs or parts of the readme for example.
Looks like a software bootcamp project, so they probably did it to save time on that bit. But you picked the wrong license if you don't want people to copy you.
Bootcamps are treasure troves of stolen projects. I got into a rabbit hole on this a few weeks ago, and you'll find the same "project" done by several different people at several different bootcamps. There were even some that were verbatim the same despite proudly saying the project was independent.
