Fro's okay, and there are times when I even look at what Ken has to say. But then there are lots of people and groups I'll read/watch.
Fro's a marketeer and, on some level, influencer. He's a photographer too, I guess. That's a funny thing to say, but I've never actually seen collections of his photos. I understand that pre-Covid, being a professional photographer was tough. Even some of the extraordinary photographers from film days had it tough. So, getting into other aspects of photography such as education, reviews, blogging, vlogging, et al, make some sense.
I've watched some of Fro's videos in the past but I don't follow him. He seems to know what he's talking about. He has his opinions and views, some of which I'm in disagreement, but that's okay. Unlike one "personality" in the photography vlog-sphere (not Ken), he's not a sensationalist. It's rather interesting that he had a video where he actually talked about meeting Ken, saying Ken's a very nice guy, though he still disagrees with Ken on many things.
Is it worth watching Fro? The fact you've only watched a minute or two of his videos says you're not interested and that it isn't worth your time watching him. Still, you could go to YouTube, look over his videos, and pick one on a topic you know. Watch it. Does he actually know the topic? Are you learning anything from it? Do you think you'd be able to learn something from other videos of his?
It's your time. If you get something of value from the time spent watching his videos, then follow him. If you think you could better spend your time doing something else, then do that.
