Yes, to answer my own question like an adult, some did!

Vince Cate moved there to work on export-banned crypto, renouncing his citizenship and would start an ISP on the island after the banks rejected his electronic money ideas. This could have been PayPal in another timeline? https://en.wikipedia.org/wiki/Vince_Cate

the e-Gold people met there on an occasion, and Robert Hettinga and MIT researcher Rafael Hirschfield started the International Conference on Financial Cryptography in Anguila. https://news.ai/ref/crypto98.html

So not in droves but it was a place, as it were.
