I think this kind of behavior is wide-spread - Climbing a ladder and then kicking it down once you're on the top because you don't need it anymore. Twitter is the famous example of doing that where they grew their network on the backs of third party clients, and then rate-limited them out of existence.
Yes, 100% agree. The problem always seems to come when there is money involved. Especially when you take someone elses money, and then get corrupted by the pressure of returning the principal with interest. You get slow-cooked into compromising your ideals, even if you personally were never greedy/malicious. I suppose that's easy to say for me, since I was never in that position :)
