OVERWHELMING majority of users
I would gues around 20.
Roughly 200 unique users on this forum alone spoke unfavorably about the mechanic (spoiler: that would equate to pretty much 95% of the people who talked about it at all), and the response was pretty much the same on Steam, NeoGAF, ResetEra, Reddit... Hell, the BG3 subreddit in particular is pretty much a den for rabid fanboys and even there the large majority of comments was absolutely, unquestionably unhappy about the chain mechanic every time the topic came up.
