Assume any acquisition without public terms done over blog post is an acqui-hire. But given the market that's still an accomplishment!
I don't understand what a company hopes to gain doing stuff like this as the (long term) incentives don't seem to align.
The executives of the firm being acquired usually don't come, unless they have some skillset the acquiring company needs. But they (hopefully) get a cash bonus for the successful acquisition.
Everything is negotiable of course.
