You are taking this part of the letter out of context by assuming all of the exhibit images are for the same purpose. Exhibit C is there to highlight consumer confusion caused by the issue -- which is relevant to a trademark dispute, because if there's no confusion there's usually no problem in the eyes of the law. They are not claiming that random internet posts means the company is officially using the name, but that posts like that are evidence of widespread consumer confusion in differentiating the brands.

And "passion" leading to "boldness & assertiveness" is virtuous, however this behavior -- documented in WP Engine's PDF complaint -- is unnecessarily overblown + harmful to the public good/business health in my eyes.

Rest is me blathering, ignore if you don't want it:

Ego is clearly, to my mind, overriding analytical fidelity on the part of that Auto-matt business. In 2022 the CEO talked about a different company in the Word Press universe as "parasitic". https://masterwp.com/mullenweg-godaddy-is-an-existential-thr... It is not uncommon to see over-reach by CEOs, which is part of the job though does often fail to pass the smell test. And, sorry to those CEOs (especially those whom I know) who are Not sociopathic, buuuuut it's not uncommon for sociopathy to be present in CEO behavior. Boldness and assertiveness are great, don't get me wrong, but the specific terminology used by MM about WP Engine, (and this is IMHO), is nutso, plus the wacky-pants lecture he gave during a social-networking conference about WP etc, according to the WP Engine complaint, was just stupid.

WP Engine seems like a legit company doing legit things in a legit manner. Their legal brief, yesterday, laid out compelling evidence of unfair (IANAL) illegal behavior by Mattttttttttt and his Auto MATTTTTTT ic company. [Talk about "naming a company after myself is right".]
