Didn't refute anything? My first comment spoke directly to the diminished options for main stream shows / shows with broader public appeal. Shows like North of North and Heated Rivalry are great to see in the mix, but they're not really geared towards main stream interests -- they focus on plots and characters that are 'niche', and which generally have less appeal/interest to the broader public. North of North is also a Netflix series, so that's arguably American origin content -- it's one of those series that gets made, and aggressively marketed via algorithms, to meet government regulated content quotas. Even more, that there's a large chunk of content that gets clipped, my point still remains valid that the standard of living / quality of life is diminished by clipping American content -- by very definition, less choice/options, is a downgrade for Canadians. What I'd been pointing out with the 'type' of content delivered by the CBC, is that the cut in content when cutting American media, is largely mainstream / content popular with the majority of Canadians -- and your examples of niche content for specific demographics, available on the cbc, isn't enough to make up that shortfall.
My second note was broad stroke refutation of everything you're trying to highlight, by simply pointing out that while you may be pontificating about this and that online, the cold hard truth is that Canadians aren't moving in great numbers to clip things like American media/American streaming services, etc. You can armchair jockey all you want, but the boots on the ground (payment cards in the hands?) say that us Canadians don't really care enough about Trump's tariffs/trade shenanigans, nor about his administration's policies, to reduce our options for streaming on apple or netflix or whatever, nor are people boycotting Amazon. Our creature comforts and convenience come first in our priority lists. Piss and moan about other options being around all you want, they're not convenient enough, or high enough quality, for general Canadians to switch.
We'd rather sell the Americans our payment networks / critical infrastructure, and then the next week make a big blustery media storm about trade deals falling through because of sovereignty. We collectively shrug and make excuses for people like Danielle Smith, who runs to the USA to discuss trade rather than siding with her Canadian counterparts - Albertans, who are Canadians, still support her it seems. We are nowhere near as resilient / self-reliant as people seem to pretend at times, and there's still no real indication that the public has moved aggressively away from American service providers, nor any indication that they would.
