What evidence are you referring to, are there recent specific examples you can point to? I thought there were a few missteps early on (for example, the initial framing of custom meta fields as 'legacy' was alarming to many at a time when the shape of developing with Gutenberg was still unclear) but overall there's a lot of very healthy engagement on the GitHub repo for Gutenberg. The FSE Outreach Program is also an excellent place to engage and be heard.
