The rise in generative AI technology has made scamming people online much easier, with fake versions of Tom Hanks, Mr. Beast, and other celebrities often appearing in online ads. YouTube still has a problem with fraudulent advertisements, as I've learned from my own YouTube feed over the past few months.
And for ad-free YouTube specifically on Android-based smartphones, LibreTube is my personal fav but there are plenty of other options such as NewPipe, Clipious, and YouTube Revanced.
