Wayne Hunt got Commodore's permission to use the amiga.org domain in 1994. The logo that is currently in use was introduced much later: it features the BoingBall and the red diamond, elements introduced by ESCOM. A quick check using the Web Archive suggests the current logo design started showing up in 2001.
Cool. I hadn't seen the earlier version.
