Probably a miscalculation. Everyone you mentioned has already publicly expressed their views towards you, I don't see why they would hide behind something like this. I would rather say that you have new antagonists.
Competitor? I know all the active campaign managers and I believe that their standard isn't such low. Do any of them have such lower mentality? I believe no.
You will be surprised. This is one of my client earlier today:
We had a signature campaign manager reach out to us a while ago about these costs but we lost their details - they claimed that we were being overcharged and I thought I'd check with you as it seemed odd. Want to ensure we're actually operating a good deal with you
My response:
Whoever was this guy, the approach was a low moral of course. A reputable campaign manager who made a name in the campaign management industry will never do such things (talking behind his colleagues). If it was anyone then it must be those of the haters. And you must know there are a lot of selective members who are haters especially the success of my campaign management. You will find some of the names here:

A reputable manager does not have that time. It's the haters sometimes become campaign manager, sometimes becoming respectful forum members and misleading the clients.
