Is this your example of Neutrality?

Heads Up  [Header, new topic]

User Borealdreams asked me for help here. He is now experiencing WP:BOOMERANG. One question; may I assume that your "my client" comment was one of your typical edit summaries and not an indication of a COI? That's what it sounded like to me. Guy Macon (talk) 

The client is installing OPGW for their own purposes, I have nothing to do with the selection of the materials - but presumably the client knows what it's doing when it picked OPGW. Mere facts will not sway a Wikieditor. Besides, I'm well known for being in the pay of the Twisty Bulb Cartel. Wtshymanski (talk) 

If it comes up, I will be happy to attest to the fact that I have never seen any hint of COI in your edits. I have other disagreements with you, but there is no need to repeat them here.
I just saw a comment on my talk page that makes me think that there is some COI editing going on. Borealdreams wrote "If the 'flat earth' mentality was removed, I wouldn't even need to mention my products directly by name". I am going to take this to COIN - probably tomorrow, I am a bit busy today.
BTW, Re: "why does a talk page for a subpage in user space even exist?", I am pretty sure that you can redirect all of those talk pages to your main talk page.
See you at the next Super Secret Twisty Bulb Cartel Meeting? Guy Macon (talk)
