eeeek not a good look, although free subscription to SKy contect and Neon for all staff wouild be a significant cost. Better delivery might have gone down less horribly.
I expect that the marginal cost to sky of an additional subscriber is quite low as their cost base is pretty fixed (broadcast rights, infrastructure and software development costs would be practically the same for 250,000 customers as for 251,000 customers)
There is a lost revenue cost, but really its nothing next to their total wage bill, it looks like they have ~ 1,000 employees, say 70% subscribed to Neon at $15/month now that they have to pay for it that's an annual lost revenue cost of $90,000.
Skys wage bill in 2022 was $75,294,000, so that's a whopping 0.11% saving there. Really not something to alienate your workforce over
