OP, just from reading the first blurb there about coinmarketcap's alleged understatements regarding bitcointalk's status among crypto forums I can see that this is all just nitpicky stuff. There might be some language difficulties that account for your claims, whether they're on your part or on the sites you took quotes from. For instance:
Coinmarketcap.com1. It did not recognise Bitcointalk as the largest Bitcoin Forum.
Today, Bitcointalk is one of the largest online forums where people can ask questions and discuss topics related to Bitcoin, blockchain technology and cryptocurrency in general. The forum was created by the infamous inventor of Bitcoin itself — Satoshi Nakamoto, in November 2009.
For one thing, f you put a comma after "forums" in the first sentence, the meaning changes to exactly what you said CMC didn't recognize. For another, CMC looks like it uses a lot of "couch phrasing". A lot of people and journalists do this, writing "one of the best/biggest/whateverest" instead of declaring absolute dominance. Calling CMC out for that just isn't worth doing, IMO.
My advice to you is to just read before starting these threads about bitcointalk. You might have fallen in love with the forum, you might be fishing for merit, but to me (and probably some other older members) it's kind of blah.
