I think there's something I'm missing - what's the io/aviation connection? I thought dot-io was "British Indian Ocean Territory" and was co-opted by tech startups looking for a domain that wasn't squatted in the usual .com/net/org TLDs
Is it just aviation themes though? IIRC, it's pretty much any generic word with a positive connotation, with little care if that word has already been used for another unrelated framework.
