Years ago I had a successful website based on the API of a growing site which has since become pretty large. The main founder/CEO was pretty prominent in the community at the time and clearly thought that he was an amazing person. His attitude reminds me of how Splez has acted to the Apollo dude... rather than think "hey, thanks for adding something to the community, we appreciate it and could work together" he seemed to think we were interlopers who stole something from them and were using it unfairly. I think for both of them there's a feeling that successful outside developers demonstrate the CEO's inadequacy at meeting the needs of users. Plus on a personal level, Splez is this nerd who looks like he's from an Advice Animal meme and the Apollo guy looks like he could be on a TV show.
