I'm not sure how Oracle really squares with that theory. From what I've seen, courting executives can work pretty well for companies widely hated by users.
They can be vocal about getting people out all the want, won't make them effective at it, especially if most people don't understand why power text editor users hate WYSIWYGs. Once contracts are inked and the whole company gets hooked on something like Slack good luck getting it back out.
Oh, it can happen very quickly.
Do you remember Skype? Everyone used to be on Skype.
Who uses Skype anymore today?
