Part of me thinks its to see what the competition is doing, see how others are using ai, to train ai, steal ideas/clients (common in the ad/marketing/design) world, train staff to hire, get free consulting.
Some say it’s to raise stock value by fake growth indicators or motivate employees that they are replaceable, but I think those 2 are just partially the case.
Another reason maybe to profile the pool of talent that probably gets hired by your competition.
