The limitation seems completely arbitrary or stems for a misunderstanding about the difference between a state and a territory. For better or for worse, Puerto Rico is virtually a state (with residents who can't vote for the president with some minor other caveats), but legally there shouldn't be any difference.
It's great to hear Stripe has solved it but remains a mistery WHY Atlas wasn't available for Puerto Rico long time ago? What's the deal? But then again @adolfojp, Puerto Rico, as we all know is US territory for the good of US, no matter Puerto Ricans, right?
Clever media play by stripe though
Stripe's move is clever but not because of the "media play" only ... they are doing the best thing an US business can do regarding an opening Cuba right now, they will see tons of cuban businesses applying right away, and I bet a very high cash-flow, what's not to like?
Also, I can vouch for Merchise Startups (the guys Stripe are partnering with), and they know their ground, that's something you can say about (sadly) too few people in Cuba, regarding business, entrepreneurship and startups anyway. So the move gets clever by the minute...

And now I see Stripe getting friendly with Cuba.
I don't have a clear point to make, as I'm writing this while still upset, but I just felt like I had to get my word out there perhaps to get some perspective or perhaps to start a discussion.
