Their streaming rights in each country is up for sale; similarly to most sports events.

Typically National TV channels will buy these rights since international events do attract a lot of viewers from said country since they as a country are being represented on a worldwide event; it'd make viewing it more easier if it was accessible everywhere and would give a huge boost towards the morale of player; but this doesnt happen all the time.

If you are in canada the whole of the Olympics are available on cbc.ca. broken down by sport, live and past event's

You'd think so, and they should be.

No, they aren't

I mentioned this in another thread : you can go to France Television's website and sign up with a bogus email (there's no check) to watch live broadcasts and replays for free !

One user pointed out to me that they may geoblock you, so a VPN would be recommended.

And then obviously it's gonna be in french, which definitely isn't ideal if you don't speak the language lol
