The Feedback Hub was introduced to fix this gap in user reports for Windows. Microsoft does actively monitor this. They respond when necessary, merge topics, deny or approve bugs/suggestions, etc. For their software, such as Terminal or VS Code, you can use GitHub issues.
Keep in mind, like most companies, Microsoft has guidelines on what employees can say when responding to any user feedback. This is why we typically see a lot of copy and paste. When it is more than that, wording is selective and you may not get more than one or two responses in total.
I know of at least one employee on Reddit who participates every so often. https://www.reddit.com/user/jenmsft/
