If it helps, I think the vast majority of people agree this guy is pathetic. The message he sent that really got me irked was when he put "least they could do".
As if producing free content, and not communicating, is somehow WORSE than having just never produced any content in the first place. (Not that this is even the case here, but that just makes their stance even more ridiculous)
If only we could all be paragons of virtue like this guy and spend our time trying to make the world a worse place by targeting those who actually produce something for others, and doing our damnedest to make them want to stop.
You keep being you and sharing content with the world! The rest of us appreciate it! And if you ever feel like slowing down or just stopping all together - you have already done more than most people will ever do and quitting wouldn't change that at all. Although it would be a real shame.
