i feel like the value you’d get from being on the Scratch community certainly isn’t worth the stress, trouble, time, and cost of litigation. if you're committed in learning to code/joining a community online, there are plenty of other ones. I don't mean to be rude/blunt, but a lawsuit would almost certainly fail, and I think you should instead get over this and move on (if you really want to use Scratch, you can still download the offline editor). :)
