There is a distinct difference in the attitudes of indifference, anarchy, and non-conformity in the MGTOW described in the article vs. the aggression, control, and exaggerated masculinity in PUA community.
I don't think this is a fair characterization for what a lot of people refer to as "the PUA community". Accurate words would be confidence, independence, and leadership. Some people choose to view these attitudes as controlling/aggressive because when comparing these actions to themselves, it erodes their own confidence or self esteem. But that's their problem and they're trying to blame someone else for it.
The community certainly helped (and helps) a lot of men who suffer from confidence issues, but it also did/does so in a very flawed way, and threw everyone else (namely, all women) under the bus.
