Anything that gets people off Facebook is in the best interest of the people
If I was an American/Euro/South American news org I'd be staffing up my Canadian journos. Any org out of reach of the backroom dealing Ottawa private school clique can probably hire some local freelancers and fill the void by the end of the year.
Regardless, Canada isn’t protecting people from facebook. They didn’t ban news sharing, they just wanted to give their media companies a cut.
