Relevant casks

mpv

mpv.app was never "official". As seen at https://mpv.io/installation/, the build was unofficial one by a third party. This was confusing as calling the cask mpv made it sound official so it was renamed to make it clear which vendor it is from. In this case, we're taking the build from https://laboratory.stolendata.net/~djinn/mpv_osx/.

can easily see someone being alarmed at seeing anything named 'stolendata' on their computer....certainly raised enough wtf in my brain to go googling for it

If something on your computer was actually stealing your data, I promise it wouldn't be named stolendata. That's just the cask author's GitHub username. Real malware tends not to introduce itself.

I'm not installing the mpv cask but I'm warned every time I run brew cleanup, which is a little bit annoying.
Is that the intended behavior? If so, is there any way I can suppress this warning?
