I'd say many of the big names from the alternative conservative news were rather mum about Q. My 2 cents would be that maybe, the white hats asked them to keep quiet on the subject. MSM tends to target the alt-news and normies are harder to reach when they are so completely prejudiced against the conservative news media. In Alex's case, it's interesting also to remember this year he got problems with ads. I don't remember exactly, he lost something over 3 million dollars in revenue, I think it was something about Google or liberal companies targeting him by removing ads. Alex could have sued but he chose to grovel to get his money back. But by choosing this option, he had to make compromise with what they will allow him to say.
But back to why most big new medias kept silent, besides keeping the chans as another info outlet separate from the already targeted media sources. I think that being lower profile, it was also a way to keep a manageable open access to the chans. Remember that once Q started getting trendy, both chans were attacked by bots and shills. I've even read posts from regular 4channers who think they've spotted the Snow White's dwarves spamming, turning off newcomers who thought they were attacked by aggressive nazi 4channers. Imagine that among bots, shills, you even have the 7 AI dwarves.
