The decentralized nature of the fediverse means nobody can "control" it really. You can have control over your own instances and that's pretty much where it stops. I doubt the Canadian government would want to run more than a Mastodon instance like we've seen in the EU for open communication.

I would rather they invest in this with a tiny tiny sum to keep open communications available with the populace as compared to being beholden not only to corporations, but corporations that are generally outside of our jurisdiction.
