A possible way to deal with that would be if the government of Canada itself set up a fediverse instance on every upcoming platform and encourage the public to use these new system through them. It would be like the CBC instance that would moderated and maintained by paid professionals and employees for the public at large.

Before anyone jumps down my throat with CBC is bad BS ... I have my own complaints about the CBC but I still believe that a publicly backed service is way more important and significant to everyone in general than in privately controlled services, even if they are just as small as one instance with a few thousand users.

I would much rather prefer a publicly funded instance that would have government or institutional oversight rather than in trusting random anonymous individuals on the internet that state that they have the best interests of everyone at heart. I can learn to trust people but people change over time and we never know where they are at or what they are doing or what is affecting them. At instance manager and owner right now might be open, capable and enthusiastic but maybe in a year or two, they would end up no longer caring or changing their politics for whatever reason. Maybe they just get bored, tired, run out of money and just hand it all over to someone with less than rosy ideals who turns the instance into something else.
