Welcome to the official CK3 forums, where the most hardcore CK2 stans and CK3-doomers roost. The former because who wants to talk about CK2 in the CK2 forums, and the later because truly who is a more hardcore fan than the 'I lost hope in this game years ago but still buy every DLC and talk about it multiple times a week' fan?
Typical forum rating dynamics and evaporative cooling of opinions does the rest. Here, a small-but-consistent 3-to-5 group of users willing to downvote or argue on any given topic can shape a significant user climate perception, especially since you can see the individual counts of the disagree / dislike X's versus approvals. In Reddit, you might not even realize five people disagreed with you due to net +/- showing. Note that this applies to the dev diaries as well, which are flooded with temporary / non-permament posters who often do nothing on the main forum, but are too many for any doomer group to meaningfully impact.
The (much) larger user base on the dev diaries, or on Reddit in general, lets pro- and anti- opinions coexist more easily. Especially on reddit you can get magnitudes more engagement in either direction than on the forum, and the CK3 reddit climate (and ignore feature) limits the incentive / scope / impact of down-votes as a forum-shaper.
