Yes, it’s just a personal opinion. I don’t like Meta at all, but I don’t think the creators will come here on their own. Besides, I am convinced that what should differentiate the platforms (even for games, movies and music, not just social networks) should be the services offered by every provider, not the content.
Also, I think they are many other arguments against federation (Is fediverse capable to moderate content coming from Threads ? Especially if Meta don’t do its part ?).
Personally, I will likely move with the content. I left Twitter and Reddit because of the ads, but I will give Threads a try as soon as it’s available in my country, and even pay if there is no alternative and the price is “fair” (unless some fediverse accept to federate). I already did it with YouTube, it’s just impossible to find an alternative and I can’t stand the ads anymore :/.
