Probably the best example I can think of off the top of my head is "Leaving Rust gamedev after 3 years", which got a fair bit of (positive!) attention both on HN [0] and on /r/rust [1]. If you look through the comments there a huge proportion of them generally agree with the article, and the top comment explicitly calls it "a good article". On /r/rust Josh Triplett (one of the Rust devs) has the top comment on the post basically acknowledging that the criticisms are valid/reasonable and thanking the author for their feedback [2].

I've seen other criticisms spawn good discussions and/or a good number of people agreeing, but nothing quite as clearly on point as that off the top of my head.
