The "linear channels" were the only profitable segment in all of the Disney Company the past quarter (that we have financials for). They offset the losses of all the other segments such that the last quarter was a net wash (that is, they didn't have a loss, but, they didn't profit $4B like they would have per quarter).
If anything, the linear channels -- which push content directly to homes -- was proven to be pandemic-proof.
And that is why Disney is all-in on streaming. It's pushing content directly to homes bypassing the middleman of cable/broadcasters. It's the future of home entertainment. And again... pandemic-proof.
Now, I'm not going to say that Disney will give up on theatrical releases. As much as Iger has said in every quarterly call since D+ was announced that D+ was their top priority, Iger equally stressed (when badgered by analysts in every call to give up the theatrical window) that Disney movies are committed to the traditional 'windows' (theaters, PPV, premium cable, broadcast/cable, DVD, streaming). Each window is an opportunity to make money from the film.
The recent restructuring announcement clearly states there still is a division producing content for theaters.
But when there are no (functionally operational) theaters, well, Disney can make an exception for a while and go direct to stream... if they think it will bring in a premium, or, increase/retain subs.
