Did TFS ever encounter any legal trouble with DBZA?

Hi! I was just scourging around the internet and stumbled across a video of Sean Schemmel being asked about TFS and he seemed very negative about it saying that it doesn’t seem to be legally fair use. He said something about taking someone else’s work and using it for your own business model, but I thought it was a lil bit silly because I’m pretty sure the intro says it’s non profit so there’s no business being made, and did funimation or toei ever tell them to stop?
