I’m in email correspondence with them. The terms you linked only apply to the pilot B2B one they were using for events over the past year. The direct to consumer one is launching in 3 weeks and it looks like I’ll be one of the first to receive it. It’s 4 year expiry like a normal prepaid card.
I actually used some Google Fu to find their purchase page that wasn’t public yet, and I was order #1004. Afterwards they emailed me and were like “how did you find that page??”
