It must've really pissed off Zuckerberg when for the first few months every popular reel had the TikTok logo and soundbite at the end.

I assume any one person's decision would rest on some kind of risk perception that TikTok becomes/remains non-viable for the given period of exclusivity.

Yes, which is why I am advocating for diversification.

If your livelihood depends on a single company, you exist at their pleasure.

This has been an unending source of frustration for me when I have followed someone on any of the algorithmic platforms vs. self-publishing.

So often many will invariably end up letting the place where they predominant publish to dictate what and how they produce whatever it is they output. (I was fighting hard not to say the word "content"...)

Which I despise but also understand: you do what anyone with a job does to keep the money flowing until someone in the relationship decides to end the arrangement.

(Now that I think about it, self-publishing is hardly immune to that. It just means perhaps the creator's motives could be more varied and fluid?)
