To be clear 4E had a lot of problems besides the lack of OGL, but if 4E was published under OGL I am not sure the creator community would have continued to support 3E and Pathfinder to the degree they did. It is my opinion that this support and the alternative it offered to gamers are one major contributing factor for 4E's collapse.
Foundry is now saying the 1.0a license is irrevocable, along with Dancy who was the chief architect of it and a Wizards FAQs dug up from 20 years ago essentially saying the same thing.
Foundry has also stated they will continue to support 5E content under OGL 1.0a. So there will be an avenue to play 5E unless WOTC wants to go to court and shut them down; a move that would likely fail in court in addition to generating severe backlash above and beyond what we have seen already. If foundry is there it is a safe bet the other VTTs will follow and small creators will continue to publish 5E-compatible material.
With a way to continue playing 5E, and a large part of the 5E community unable to transition to ONE because of the new OGL, I think it is likely that ONE will fail.
