None of what you said is true, except on YouTube. Facebook does not respond kindly to false takedown claims and unlike Google will revoke someone's right to use the online reporting function (meaning that future claims must be filed the old fashioned way, through a document or other means of communication that exposes the complainant to legal liability if they make a false claim. Twitter is generally the same, as in 280 characters you can't meaningfully infringe many copyrights. This is not textbook abuse. It's literally just Facebook making a bare statement about copyright licensing.
