A Youtube competitor would be GLORIOUS.
If anyone can do it, Elon can, but I don't have high hopes. I really wanted to go to Rumble, but compared to Youtube, the place is an empty wasteland. You can find stuff like non-woke political content, but things like, "Where are the zerk fittings on my 2020 Polaris?" just aren't there.
I blame much of that on Youtube monetization. I remember pre-monetization, all kinds of people posted how-tos and similar videos just because they wanted to share information. Now with monetization, you're just not going to get a lot of those people moving from Youtube. Sure, the random guy who just enjoys talking about gun stuff and doesn't care about money might post on Rumble or wherever, but for people like say, Demolition Ranch or Garand Thumb or whoever, they don't want to give up the money generated by their millions of subscribers, and I can't blame them.
Of course those are examples of the kinds of content creators that you need to jump ship from youtube to get other people to follow suit, and thus bring viewers with them. But I have seen Warrior Poet Society, for example, had started to post like 10 minutes of a 30 minute video on Youtube as a "teaser", and if you wanted to see the rest, jump over to the WPS Network and sign up for their service and give up on the big tech. It must not have worked, because they're back to posting full videos on Youtube. The Googles is just the behemoth.
