DivestOS has ceased maintaining Mull if I remember correctly. I use Ironfox on Android now.

I’d pay for Youtube if Google would guarantee to not track me. I donate to open source projects that I use, rotating every month whom I choose to donate to. I even donated to Manjaro recently even though I don’t use it any more, but it was something I had used in the past and I was poor and couldn’t donate them then. But I refuse to feel any guilt for watching Youtube for free.
