Not sure why anyone would rather pay Google money vs simply installing YouTube revanced. If that ever goes away (it won't), then I'll just go back to Firefox + extensions for YouTube on mobile.
I have an account I bought from an Indian friend for around $20/y, and the only way I use it is for my TVs. They are "smart", but not android-based, causing me to not be able to install smartube or the likes.
Unfortunately that isn't usable for non-tech relatives, which is why I had to give up on setting up YouTube ad-free for WebOS recently. None of the permanent exploits seem to work anymore.
I just skipped that and went straight for firefox with ublock. It's not as good of an experience but I thought fuck it. Youtube's going to fight these app solutions every time, but they probably can't make Mozilla remove extensions. Plus I don't have to be worried about logging my google account (even a burner) into an unknown dev's app vs mozilla who I trust more.
That's a good point! I had trouble sometimes getting background audio to work after closing the app, but this was over a year ago at this point before I switched to vanced (and ultimately revanced). There is probably a fix for that by now.
