Logan, I believe propietary software is «at least one of» the right term(s).
You can't explain
with ONE word all the phillosophy. I mean, we could switch to a lot of words and
grasp different meanings and truths. But in all cases we'll be leaving
some other meanings and truths behind.
As it has already been pointed
out by Felix Posselt, what we need it's not a different word «or I may add,
even a completely new one». It's all about throwing a few sentences and
see what else needs to be said (it varies within public and/or people).
Cheers.
