It is somewhat different. AirBnB founder Nathan Blecharczyk was not shopping around, but rather at some point he was the largest spammer in USA, where even FBI was interested in his dealings. Interestingly, the 3 articles I was able to find on this subject some 5 years ago (and posted to HN at some point) from major news outlets, are all gone now.

I think hurting your own business versus being a scumbag scammer will get you much different treatment, even from PG.
