So, why do you suppose this is?
I'm currently signed up with my personal email address hello@myname.com and want to use something more anonymous. Is it possible that this is exactly the kind of thing they are trying to prevent?
I used to exploit this phenomenon to get premium campsites at a state park. Sale dates were 30 days out, but reschedules were possible up to 45. So I’d book the magic campsite early, then pay to reschedule before the sale inventory was available. There’s a million similar issues that you can find if you have a knack for it.
I have no information specific to OpenAI, but if smart people do dumb things, there’s often a reason.
The bigger problem is if you lose access to an email address and cannot change it. I’ve lost access to email addresses so would be in a bit of trouble in this instance. If a paying account and continued billing even more so
this is my personal assumption, observing the golden rule like the other commentor mentioned, this most likely isn't something nefarious but most likely a low priority that they will work at a later. They're busy trying to keep the spotlight in this cutthroat hype cycle and I think it's safe to assume they're busy pushing new models like we saw gpt-4o than low hanging fruit QoL features that might even risk breaking things. You mention how they "flat-out" refuse to answer the question but I think it's reasonable to think that after yesterday's announcement they're swamped with messages to focus on this right now.
