They censor out THG because Tom (1) claimed to have discovered the fault in the 1.13GHz P3 all by himself when in fact Kyle and Tom worked together on it and (2) because on 9/11 Tom made some very negative and uncalled-for comments about how HardOCP published information about the attacks on their front page instead of sticking to solely hardware news.
They censor out Everglide because E-glide sued Kyle over the Ratzpad. It was an ugly, messy lawsuit and even though Kyle eventually won because he could prove his patent was older, it still cost him thousands in legal fees.
Forums like AT here and the H are privately-owned. You don't like what they offer, don't use them. I don't care for the H forums anymore either, but it has nothing to do with those 2 issues.
