We get the symbolic reason. It’s still overused and lazy because it doesn’t even relate to the project itself except for its origin in the most generic way.

They could at least use PhoenX or FenX to link it with X

It's a great name but way overused. I guess everything these days rose from ashes of past failures. Sector is highly competitive.

Ya, and that's the same reason all those other projects picked this name too

Not in the case of Elixir. It’s a play on BEAM processes being revived.
