Which one in particular? Their mechanical keyboard reviews seem fair (e.g. rightfully calling out the Drop Sense75 as overpriced). Of course they don't cover the more niche enthusiast boards, but their takes on mainstream boards are about in line with the community's sentiments.

Their glowing Keychron Q2 review is what got me into mechanical keyboards so I'd argue that they're doing more or less the opposite of gatekeeping.
