eOS has trademark issues. Same reason that elementaryOS doesn't use it and actively discourages users from doing so. Though... users call it that anyways.

OP is right - they should really fix their name to address all these issues: (1) Search engine-ability. Zero people are going to be able to discover this. (2) Unique domain name. e.com/io/whatever is already taken (so is eos.com). (3) Not trademarked.
