I'm unethical because I create websites for paying clients that is custom to
them? I'm also unethical because I think that the BSD and MIT licenses are
just as important as the GPL ones? I'm unethical because I use free software
to develop and deploy on the web? I'm talking Aptana Studio to code PHP or
Python utilizing MySQL or MongoDB with a hint of Redis served by nginx.
For my future sites, I have though about a free software license for my
JavaScript. It's just that for sites that aren't my own that I have to be
careful about their custom code they paid for.
You may not understand since you are simply an academic in a European country
where you rely on the tax payers to make your existence relevant without any
real life experience.
