It's the opposite of an acquisition.
It's literally:
"I don't want you and your 200 tensorflow/pytorch monkeys. I just want your top scientist and I need a clever way to offer him a nine figure salary. Good of you to grant him so much stock and not options. Now I can just make a transfer to your shareholders, of which he is one! Awesome! Now I don't have to buy your company!"
I'll give you bonus points if you can guess what happens to the worthless options all those TF/PyTorch monkeys are holding?
Guys, seriously, be careful who you go to work for, because chances are, you are not the key scientist.
