Pinned thread at the top of the forum states to please use the correct sub-forum for your posts. You made a suggestion outside of the suggestions thread so it was moved. Within the suggestions sub-forum is a pinned post for "Popular Community Suggestions" where the fourth suggestion down is "Pause in Singleplayer."

Neither you nor your feedback was censored, you just didn't follow the rules of the forum and your feedback is something they have heard so many times it is acknowledged by the developers.
