Sounds like MS, that is the only way they can get organic customers. All their popular products are originally built by someone else except Windows of course
Buying products though is very different than buying customers; if we try to map this hilarious customer "acquisition"--which is now a double entendre ;P--strategy to a more typical product, it would be akin to saying "no one is using Excel, so let's start buying large accounting firms currently using VisiCalc to migrate over".
I sometimes think MS product owners are on coke all the time or something. Last week or so i was in the middle of a conference call and MS teams just decided to restart itself with a new update.
The thing that made it the worst for me was the inconsistency across devices, such as only being able to directly reply to messages on the web and phone app but not the desktop app (at least on OSX).
