I’ve had so many issues with Ubuntu in the last few years compared to other distros that honestly I wouldn’t feel comfortable recommending it as a beginner distro anymore.

I think you meant “concerning”?

Sorry but I don’t see anything particularly egregious in there. It’s all fairly common stuff, any sufficiently big company is going to face some lawsuits of that sort at some point. Also, remember that anyone can file a lawsuit, it doesn’t mean that the recipient is guilty of what it describes or that the filer isn’t just exploiting technicalities.

Nothing there blatantly screams “bad company” from what I can see.

You don’t master Javascript, ever. You just become accustomed to the madness and stop caring, while sometimes doing things right.
