But now the verified account can be like: ooo wow, we are totally humbled by the love for our product thank you so much you guys!!

For guerrilla marketing techniques sure

But for official advertisements I imagine they would want to do them on a verified account.

Have on official account to post announcements then bots to upvote it.

They would of course keep their astroturfing accounts unmarked, of course. But they might want a corporate mountpiece account. Like they have on twitter.

ive seen in the nreal, now xreal, sub where having people from the company to talk to about issues helps. im not trying to market anything but just use an example. i doubt thats what they are going for but it can be a positive side effect.
