I already complained about post on reddit. It says that link to RSS is hidden, which is not true IMHO.
YouTube page contains HTML link to RSS feed in channel page, and most RSS clients should just pick it up just fine.
By the way I maintain a list of feeds, many of them are youtube in link below, so if you would like to find a channel you can use it
Links:

Hidden is a pretty reasonable synonym for "not visible".
no, the paragraph argues that something needs to be glued together, which is not true, so it is not entirely about 'visibility'.
