(I haven't checked the OpenAI one, as I have no interest in them)
I expect they haven't decided that themselves yet and don't want to commit publicly until they've seen how well the program goes.
You know what they could also do? Stop the programs for new enrolments next month. Or if if they renew them like you said, it could be with new conditions which exclude people currently on them.
There are too many unknowns, and giving these companies the benefit of the doubt that they’ll give more instead of taking more goes counter to everything they showed so far.
We should be discussing what is factual now, not be making up scenarios which could maybe happen but have zero indication that they will.
