Thanks for the link, I didn't know that was a thing.

Having said that, this sounds like "Hey guess what? We are gonna snoop on you, and profile the hell out of you and leak all of your sensitive data all over the place (filenames can be) all because you are a paying customer"

That's about the worst way to disrespect a paying customer. Is there a way to easily identify companies that does this, I can avoid them?

No, they don't need to snoop on you. Just fire a single pixel saying this is a user that they would like to find more of. FB does the rest based on data in FB, not on Backblaze. The mistake was them just adding it to the online dashboard because that's the easy way to automatically include paying users.

No. And this can happen for a lot of reasons as explained so even harder to check for.
