Ethical criteria are not high on my list, but I try to apply them to the best of my knowledge when two competing services both meet my needs. E.g. LibreOffice vs Microsoft Office, and Starbucks vs local coffee house (if you count that as tech related), I tend to have an ethical preference for small and/or local businesses: I think it benefits me to support diversity and the local community.

Some nice tech companies that I'm aware of:
* Hog Bay Software
* 7 Generation Games
