Companies like this really are failing to think long term. AIs cannot create new content. All they can do is rehash their training data, because they're effectively a glorified autocomplete. So in a few years time, Stack Overflow will have new questions on it, some of which will relate to new problems. Those questions will require humans with real knowledge and understanding to answer them, and where's the motivation for anybody to do that if their answer will immediately be fed into an AI? In the long-term AIs will be useless because they can't advance or update without new content, and humans are being disincentivised from creating new content by companies who want to make a quick buck selling their content without compensating them.
Depending who you're talking about, they don't. If the bosses can find a way to bring in some extra money and then leave after 6 months or a year, they got what they wanted.
