Sad you're getting downvoted, I was thinking about this the other day, if nations really want to limit applications on the internet, they need to create a free to use high quality national alternative, and personally I don't think this is an awful idea. Canadian "twitter" provided by a gov entity? I would for sure be interested in that. The ability to use a home grown twitter that I needed to use some government ID to log into and had been thought about sensibility, at least then I'd know what I'm getting myself into. I'm not saying it should replace regular internet, just that I wouldn't be apposed to more controlled nationalized alternatives. I'd like to talk to fellow Canadians, in the "comment section", in a manner that I know with over 80% confidence they're actually in Canada.
You can make your own Mastodon instance where you could possibly/probably have verification required to approve members based on some Canadian IDs - but it sounds kinda overkill really.
Good luck finding anyone else bothering to use it. Twitter isn't just some computer software, it's also network effects and the couldn't-have-been-predicted product of a competitive market. How would the government service be known in advance to become a Twitter and not a MySpace?
