Read an interesting thread on HN. The comment that stood out the most to me was this one, and the ensuing discussion around it:

Successful companies also attract gold diggers. When the company is small, unless everybody is going above and beyond the call of duty, it’s likely going to fail. As the company gets bigger, there is more and more latitude for failure. At some point it is successful enough that it can survive having people whose only goal is to direct a large amount of money into their pockets. This can lead to really weird decisions being made as people try to kill off “competing” projects, or to sabotage other people who are interfering with the flow of money into pockets. If you happen to be the hapless person who is innocently trying to make the company successful and who is not paying attention to where the money “should” flow, it can be quite painful for you. Of course, you will always be comforted by they near-apology, “It’s nothing personal. It’s just business” as they drive you ruthlessly into the ground.
