Well doesn’t that say more about the inability of the country to produce its own tech environment where their own citizens prefer media produced by foreign companies?
Though, i'd argue it has nothing to do with the fact that they should be taxed appropriately in Canada. It replaces revenue from TV distribution that was appropriately taxed. Similar discussion to whether we should tax robots labour i think.
Also, I think countries have the right to promote their own culture. That might be hard to see from the POV of the country who's culture is slowly boulderizing that of the rest of the planet.
