Someone who obsessively and loudly complains when plans change or things do not go their way. They commonly make a lot of noise causing major distraction to others.

Coined by CIG in January 2022 in response to backers of the game Star Citizen after complaints about repeated delays on the roadmap development progress.

A large contingent of Roadmap Watchers continue to make noise every time we shift deliverables.
