Support Manager (and person who wrote that line) - it's certainly not meant to be dismissive or tongue in cheek. If you've got some suggested wording to help take away that feeling, I'm happy to submit (or merge) and MR to the blog post to make it feel less that way.

We actually do want (and care) about your feedback and wanted to provide a clear way to give that. In the past we've gotten support requests, tweets, comments on GitLab issues and a myriad of other creative ways of voicing thoughts, opinions and ideas.

My hope was to streamline feedback into a single place that GitLab support and our community teams are actively monitoring. There's been some helpful discussion there (and here) already.
