YouTube restricted video featuring competition

Some years ago I have uploaded a video featuring some VOD platforms available on the market (like Netflix). It gained an impressive number of 170 views. Yesterday I have received an email that the video is now age restricted, and is not visible for not-registered users. The video does not contain content not appropriate for children. Appeal was rejected immediately. It is interesting, that a video featuring YouTube competitors that no one really watched for years is blocked out of nowhere without a valid reason. I am curious if anyone else noticed such actions.
