Subscribers was the metric because that is revenue and market share. Nothing much else beyond cost matters because subscribers are paying the bills.
The problem with your proposed model is that you are cannibalizing viewers. There's a lot fewer people willing to pay $8/mth for getting content 18 hours early than people willing to pay $8/mth for exclusive content. Without the exclusive content, the value of the platform is diminished. Same thing with licensing to Netflix. It's no longer exclusive then and there's even less reason for me to pay for the platform.
Disney's big mistake was trying to compete with Netflix instead of licensing to them. With licensing, there's no risk. It's free money. They could partner with them to develop original content like Mandalorian under license. Netflix foots the bill and gets the content, Disney gets a small cut and maintains the rights after a certain period. Everybody wins
