Here is the license.

Custom license that doesn't meet the FSF's definition. Tldr restrictions on redistribution and minor restrictions on modification. It isn't on fdroid's main, but they host a fdroid compatible one with a out of date version of Grayjay

It's on fdroid so I don't think

NewPipe stops working whenever Google updates YouTube with a breaking change that NewPipe needs to integrate then, e. g. renaming parameters, changing URLs and the like.

NewPipe has been steadily working for years, with the expected interrupts as they have to play catch up with YouTube. That typically only lasts a few days, sometimes hours, though.

Neither newpipe nor libretube work for me anymore for a while now.

...except NewPipe doesn't work.

I use their mobile app and everything works like a charm.

Have you tried a different instance? I was able to use the US one with no issues at all.

hot spring for hate content

As with every platform, even Youtube. Bc even the most advanced algorithmic moderation has its limits (i.e. they can't pick up steganography nor subtle/creative language; in best case scenario, YT algorithms can barely understand a Caesar ciphered text), so it'd need manual reviewing, but there's the catch: a platform can't have strict manual reviewing AND be free, because human moderators have their costs. When a platform gets troublesome with excessive ads or oversensitive filters (Tom Scott has an excellent video regarding the problem with "vulgarity filters" when they're set to pick up any "forbidden" words amidist a text without considering their context; e.g. a content that says about "cumulative sum" (a mathematical and statistical concept) gets blocked because how the three initial letters form a vulgar word, and this could get worse if one's talking about NumPy's method), two kinds of people will tend to migrate platforms: those who simply have zero patience with intrusive ads/excessive filtering (imagine a PHP developer not being able to upload/search for a video that uses the PHP function that breaks a string into array, because the function name is "explode()" and it could be seen by filters as "violence"), and those who want to distillate their hatred. If there's a sufficiently well-known alternative platform, both kinds of people will tend to migrate there, until hate content becomes a gigantic problem and the platform starts to employ human moderators, turning the service into a costly service that'll either need to be paid or need to have ads (except if they somehow manage to work the services through volunteering, such as GNU). Odysee is one of a myriad of video platforms where anyone can create an account and upload any video. Odysee is not the first only containing "dangerous contents" and neither will be the last.

The blockchaim & finance topic doesn't really affect me, as long as I can use it for watching videos then it works. (and I'm not helping google)

In regards to the hate content, I would rather have the ability to self censor these things (mute/block) then have the platform itself decide what I am allowed to see.
