Unfortunately they're trying to get you to subscribe to both Peacock and NBC Sports Gold. Most of the tops 6 teams matches going forward will be shown only occasionally on Peacock.

I agree but that maybe only for this PL season. I think they are gradually moving subscribers to Peacock and assuming they would only exclusively show all live PL games on Peacock service from next season onwards.

Interesting! The lower UK leagues are streaming on a shared platform called ifollow internationally as well.

You didn't get it for free. Comcast owns NBC and bundled something into your internet subscription that costs them nothing incremental.
