It's important to note that currently it's in early beta, and in order to avoid playstore and apple store issues you only have access to a curated list of peertube instances.
So for example you can't connect it to your personal instance ATM... This will be available likely on a fdroid version or more widely after they manage to jump the official stores hurdles.
Personally, I don't this will have much success because titok is driven by algorithms and influencers...it's built for lazy scrolling consumers that follow the latest trends. People that use it don't care about the data privacy or ethics of it, they just want to know what the latest song or dance craze is ... Add to that ease of use to add graphics and music tracks. Also reach is everything.
I saw this coming, with no easy way to cancel the monthly subscription and decided to pay with a prepaid credit card instead...glad I did, it saved me from getting robbed.
I thought that only shit hole countries did that;)
