Canada

I really like the idea of opting out of IP agreements, but it's unclear how effective it would be. AFAIU jail breaks are illegal in the US thanks to the DMCA - if Canada produces the kits, it's still a risk to American farmers/Tesla owners to use them.

And:

But you know what Canada could make? A Canadian App Store. That's a store that Canadian software authors could use to sell Canadian apps to Canadian customers, charging, say, the standard payment processing fee of 5% rather than Apple's 30%. Canada could make app stores for the Android, Playstation and Xbox, too.

This requires cooperation from the platforms we're attacking. The EU had the clout to force Apple to open their platform, but would Canada? Would a bellicose US allow one of their most profitable and iconic companies to do that? Given a choice, I suspect Apple would happily make the "alternate app store" experience so user unfriendly that most users would avoid it.

Android has allowed side loading forever, and has a bunch of non-Google app stores, but they have only gained traction in limited circles.

It's a fun idea, and it'd be interesting to see how it works out, but I'm not sure it would have a significant impact.
