First, I should say that I don't think a Canadian information environment should be or can be fenced off from national borders, so I don't think there will be a company that is solely Canadian. The investment of resources and time to generate an environment that would provide a meaningful alternative to what currently exists would take a generation.
My argument is that there's no time to lose. Canada has to work with like-minded, trusted allies and partners. Whether it's a social media platform or whether it's AI systems, Canada has a position now to really drive this debate with, say, Europe and other non-American Five Eyes partners to create another ecosystem.
Yes, some of that will involve private companies, and those private companies may indeed behave in ways that are different from how some of the American companies do. Some of the American companies behave differently from Meta, as you identified. Google reacted differently, ultimately, than Meta did.
However, when you have an information environment simply dominated by American media and platforms that also disincentivize the sharing of Canadian news sources, that is not in service of Canadians' being well-informed about what's happening here.
This is really the crux of my argument, not that Canada must create a Facebook equivalent that's only owned by Canadians and has no foreign users. That's not the vision. The vision is more that right now, decisions are essentially made in Silicon Valley on behalf of Canadian interests. I don't think they're actually working on behalf of Canadian interests.
