I suspect it's also a defensive move.
Imagine you make a widely hated product targeted at huge corporations. Workday, Jira, Oracle Financials, anything like that.
Then you find that all your users are using ChatGPT to automate their interactions with your product. Instead of your product being crucial to your customers' business and almost impossible to replace, it's turning into a dumb pipe connecting LLMs - and looking very much threatened.
After all, data lock-in is a core part of your business strategy.
Getting people to use your AI tool, though? That makes your product stickier, and lets you charge more too.
not for jira, that things ai is garbage and gets in the way most of the time (and same for a lot of companies imo)
