good catch,there are many reasons why YT does this, suppression is one reason, (its a Q linking) other truthers same reason, plus it is about advertising money paid out according to views, its real shady what yt does
there are at least 5 reasons i know of in different ways and there is probably 10 more i didnt even think of as to why they do this,
some they give view counts to, bumps them up the search, gives them money they took from others for whatever reason, etc…
