@mattb @ariadne @eff If not corporations, who? The US and Canadian governments? Then there are clear First Amendment issues.
Look, ISPs were blocking the websites of their own workers unions during strikes. Their right to do so is precedent. Facebook (which has monopoly position) is blocking all Canadian news to retaliate against the government.
We're not in danger of sliding down a slippery slope, we're at the bottom watching the worst people demand privileges to stay at the top.
