There is a non-trivial number of people who get an adverse reaction to anything technical, including the language of technical - numbers. Numbers are the language of confusion, not getting it, feeling inadequate, nerds and losers, stupid math, and the "cold dead machines".

The thing is that people who are fine with numbers will still use those products anyway, perhaps mildly annoyed. People who hate numbers will feel a permeating discomfort and gravitate towards products that don't make them feel bad.
