I think some of that vibe shift was happening anyway and the Trump presidency just pushed it into overdrive as the numbers were all pointing towards easy gains from doing that (similar to CNN's high ratings throughout his presidency).

Pitchfork following the 2015 Conde Nast acquisition was the actual point where it drifted off imo into being wildly predictable with what it would champion.

Several others (most notably for me the avclub) had had several years of struggles then a very abrupt and marked decline in content with Univision acquisitions circa 2015/2016; eventually blurring into a uniform kind of sludge that seemed to intentionally blur the lines between several once disparate audiences. Meanwhile attempts to create new outlets for the content that had been ditched tended to commercially flop (e.g. the Dissolve)

Relatively speaking Vice was a lot better than most of these outlets in that it would still occasionally have some good content, but I guess this was largely due to the value of its brand ensuring it weathered that wave of acquisitions.
