Canada demands Meta lift news ban to allow wildfire info sharing

Not really emergency notifications but news, which tbh isn't as important in this case because non-Canadian news orgs aren't affected and are covering it too. So there isn't an immediate risk I don't think.

As for the main point: The problem is that a subset of the population ONLY gets information through one platform. The only way to reach them is through that platform, and not reaching them means excess costs when you have to rescue/treat/otherwise deal with the fallout. It's also the government's job to inform people and keep them safe.

At the same time, the companies need to be regulated by the government. Can't just let them have free reign because they seized control

It's unreasonable for a social media platform with almost 3 billion people to be privately owned.
