You are not the only one dismissing toknormal premise in its entirety, there is just too much baseless assumptions with toknormal and too much presenting those baseless assumptions as facts.

With regards to your last question, he is indeed a masternode owner (he admitted that publicly before), which makes his crusade against masternodes and its owners all the more weird to observe. Everytime he was attacking them, he was basically attacking himself. It would have been funny, if it was not so very twisted.

I too think he has an agenda, i think he wants to find support here to hard fork Dash into a more miner-focused coin. That is the only explanation i can think of why a masternode owner like him, is so focused on trying to discredit Dash masternodes model on a daily basis.
