I've done a few acquisitions, one of them they just couldn't believe we only wanted some ip and not their vision no matter how explicit we were. I think it's hard for some people to see themselves that way, everyone is the hero of their own story as some say. another it was a lot more obvious, esp after who we didn't keep. But I still spent some time at the pub with their leads talking and trying to pivot them mentally.
You're lucky if they want either the product _or_ the vision. Quite often they simply want the team or the void left by the market position the acquisition used to have. Of those two, the acquirer wanting the team is better but if they want nothing but the team odds are the team has little reason to stay other than golden handcuffs.
