In my unasked-for opinion, he should absolutely give up on this project, and take a salaried job that'll let him support his family and not have to deal with the entitlement issues and lack of perspective the community evidently has. If half of what's in this post is true, he's shown admirable restraint: I'd have burned it all down the first time someone got pissy about a free thing I gave them.
Sadly this is the state of open source projects. People feeling entitled and doing nothing but complain. It's sad really because negative compacts often have a more lasting impact than positive ones.
