The author is wrong. The CEO perfectly understands Stack Overflow. What the author of this blog doesn't understand is that the CEO is pursuing a perfectly valid strategy: maximize its short-term gains by squeezing it unsustainably with the latest hype, and take the money, and run. The good of the community and the well-being of the users are completely irrelevant in this strategy.
Why is this so common with tech companies? I'm not an economist by any means, but I never hear of McDonald's, Honda, Home Depot, etc. etc. pulling these kinds of stunts. They're perfectly happy being large companies that pull a constant year-over-year profit. Meanwhile tech companies seem to deliberately have a lifespan of years, not decades, with rugpulls like this being accepted as the norm.
Ex : Microsoft (evil), Oracle (not innovating and evil), IBM (not innovating), Apple (evil)
Being a startup is seen as "good" by many people because you're seen as "trying", if you stay long and raise your prices, you're seen as "milking".
Microsoft is creating a lot of innovation by trying and failing (Windows phone) or succeeding (Office 365) but many people here see them as evil because they ask for money.
