We discussed various naming convention when Hive SBI was forked off from Steem Basic Income. At that point, it was already referred to much more frequently by the acronym, and we decided that fitting a name to the acronym would be better for brand recognition going forward. So there is SBI and Hive SBI.
Also, somebody snatched the hivebasicincome account as soon as the hive fork was announced, before we could get to it. We grabbed a bunch of other accounts that were name-adjacent, but nothing that we really loved was available. So we opted to stick with the original accounts that came fully loaded with HIVE airdrops that we could put to use supporting our membership!
Ah dang username snipers!
Makes sense then and I appreciate the history. Always curious about how it all goes down and why the usernames some times.
