If people don't like the escrow, don't participate in the campaign. Simple as that. He shouldn't be forced to use a certain escrow, bitcoiners should believe in freedom.
I can not tell about others. If they are pushing or not but I am not pushing OP for an escrow. All I am suggesting him is that if he really wants to use an escrow then go with a trusted one instead of someone who has tons of red tags and is creating drama instead of really having the service.
OP is free to run his business however he wants. He will be fine as long as everyone who joins his campaign gets paid for their participation.
