Im not taking any revenue by mirroring channels, video and channel descriptions always include links to Patreon or whatever the original creators have for donations. Its no different from watching on invidius or revanced, except that google isnt hosting the content, i am.
Youtube is the the one robbing creators by giving them fractions of a cent for every dollar they make in ad-revenue and using their power to control what content can and cant earn revenue.
If a creator asked me to stop i would but i dont see that happening when its literally just my own private archive that might get maybe a dozen views on a good day.
