I was speaking specifically as to why I think Sony/Y&R wouldn't want to stream on YouTube.
I think if even Y&R were to permanently go off the air, say, this summer, they'd be more inclined to sell/stream seasons on a digital platform (especially if they could get paid for it) than P&G ever was with their soaps because unlike P&G's most celebrated soaps, Y&R has its full library of episodes from Day 1 preserved and intact, no missing episodes.
It's a good point you make about not having enough current episodes to fill their time by the end of spring but CBS has that All Access platform so should they wish to stream classic episodes, there is a ready-made platform. There will probably be complaining as there always is among some soap fans who want their soaps delivered on network television but for the rest that are glued to Netflix, Hulu, Disney+ and the like, if they haven't completely dropped the soaps, they'd probably be open to watching some classics on a streaming platform.
