Hardly surprising in a pandemic, when people with Sky are already paying a fortune for their TV subscriptions.
Plenty of people in the UK and around the world watch the PL because overall it's a good product, not just because of United, City, Chelsea or the other 3. Will it be diminished without these six clubs? - yes, obviously. Does that "kill" the league as a viable concern as was suggested in the post I replied to? In my opinion, no. There are clubs outside the top six well resourced enough to still go out and buy quality players and as such, the product will continue to be viable. Rich owners will still come along and invest in what is a marketable product.
And another, obvious point, is that City were Southampton until someone pumped a load of cash in. Now there are people in China walking around in City shirts.
The idea that people will simply stop watching the PL if these clubs leave is, in my view a nonsense. There are millions of fans out there who don't support those clubs, and millions of others who just love to watch football. The quality of the league will remain high enough to attract those fans.
