"Comms app" isn't exactly what I expect to be 'atomic', or 'simple', either. Aaand "Element Matrix Services"? bitch, please... XD
'Element' is so un-cybery, feels dated. First association is Bam Margera and teenage skateboard consumer culture. The uncool one, lacking punk rock and attitude. Such a 2000s word.
Anyway, naming things is hard and annoying, so I am glad they found something _they like <3
IIRC, I saw in a discussion somewhere that most of the math related names are already taken, and Vector was moved off of for search rankings or some such thing.
