You will find pretty annoyed people if you search for "report hipchat bug".
Google for example makes it 1000x harder to give feedback and report bugs, which greatly limits the amount of quality feedback they get.
Anecdote: hangouts didn’t let us accept external users into a hangout today. Google will never know that because I have no easy way to tel them that.
In what world would one imagine that a suggestions box was in any way different from reporting a bug? "Suggestions box" is a bug report but renamed to be understood by Joan from accounting.
So you could try to get their attention to the bug of "when you paste XML into a code block, it replaces it with subtly different, broken XML, my suggestion is to stop doing that", but it's going to be sitting several pages beyond "please add a left shark emoji!!!"
You can try to get your whole office to stack the vote, but why? I only have to be one person to report a bug to Slack.
