geez ..what a nightmare... wikipedia...youtube...internet archive..wayback machine...
Is it even possible to store all media content world wide in one giant cloud or will they only check meta data?
Canada has an interesting take on copyright... Say....you purchase a movie ...a music album...a game... whatever... you do not have a right to disseminate the product you bought ...share it...that is...or profit from it... but ...say you lose or your copy is destroyed...allowing one to get another copy is allowed...
Paying over and over and over again for something one has already purchased ....is truly criminal... Respect of copyright laws is important... But there are extremes that are too much... If stringent enforcement is the end result... then ... eventually ... no one will be able to sing "Happy Birthday..." it is copywrit after all....
and that is just the beginning... stringent enforcement could result in ...say... you bought a film..or an album...or a song. you as in "you"... watching / listening to it with others who did not pay for it ...in the privacy of your own home... could be construed as copyright infringement through illegal dissemination of content...
