There are rules about that. NetFlix funds their own shows so they're typically not forced to make them available. In practice, it's mostly a US only company and they relicense most of the productions to other networks around the world.
For example, NetFlix France is a joke, you couldn't watch any netflix shows because they're not available, they sublicensed to canal (the main paid TV service) with exclusively and are left unable to serve their own TV shows.
The Epic Store (and Steam) are global. That's more than 200 jurisdictions with different rules on anti competitive behavior. They are preventing competition globally and systematically, this has to be breaking some rules somewhere.
