CBS ending up owning 10 isn’t really relevant:
The only way I’d see it happening is if somehow the situation came up again, so 7WM going under with Comcast at the time being a major creditor & seeing that taking over 7WM was the best way to recover their money/minimise their losses.
(Hopefully my attempt to post my reply in the Seven West Media thread works…hmm…
