I don’t see it from competitors nor do I see the long string of terrible complaints, handle your business in advance this doesn’t have to happen.
(It appears that Gitlab actually pays some of them to do this as part of their job, whereas for others it is not in their job description).
But yeah my team (of 3 members lol) was spun up primarily because Sid our CEO wants to make sure that everyone in the company is plugged into what users are saying about us, and he cares about hackernews specifically since GitLab was founded here [1]. So my team mainly just triages mentions about us so devs/managers/etc don't miss feedback but can still focus on their jobs. I do see first-hand that everyone in the company really does care about what people are experiencing.

Not calling you out on this personally, just noting a general trend that's become really common the last few years.
