It'll be interesting to see if other providers including Sky/NOW TV and other European providers will provide a similar FTV service as the crisis continues?
I would suggest that mass isolation will be enough of a strain on their infrastructure as it is!
For Sky TV through the satellite it makes no difference whether 60 people are isolated or 60 million. Just as long as the uplinks are working and the hardware under the telly's working as the signals are broadcast anyway. Same for Freesat.
Now TV may have issues but they're dependent to an extent on your broadband provider, which they have no control over anyway.
Considering Sky have recently changed all their prices in an upward direction as per usual and people are peeing and moaning on various forums about having no live football and "can I cancel because of that" (answer: no), Sky could turn it to its advantage by doing a Canal+ and giving everybody shed loads of telly for the price of whatever they're currently paying. But to be honest we're probably more likely to see this:
I await to be surprised though but I won't hold my breath.
