Suppose I take http://libregamewiki.org and copy it completely (logos, attributions and all) and put it up on the .com address. Remove the license and puts some ads on there.
You'd just say "oh well, fairplay"??
Your LibertyGaming blog pages too use CC-BY, that only works because you have control via copyright law, without copyright law I can use your content without any attribution or say by you.
Personally I don't think it's morally right to profit from others hard work. Are you saying that you're licensing me to use any intellectual property you create or hold?
I think you need to qualify your argument somewhat; almost all companies across the globe profit from their employees hard work. If they didn't the company would quickly cease to exist.
Yes, it's a rather poor and limited statement which in the basic reading I wouldn't support - I clearly profit from others work on electricity generation, computer development, ..., etc., etc., etc..
Companies profit from their employees and some even are fair about remunerating their employees.
It is unfair remuneration or profit in which the profit shifts markedly away from content creators which I can't endorse.
In this limited scenario the GP was effectively asking why I didn't rip him off. I didn't want to get into the depths of it, in short it's because I think that it would be immoral of me to take his work and without adding any value take away any possible "profit" from him. Such profit includes the ability to spread his moral ethos with regard to copyright as well recognition as a content creator and enabler for free-libre content and of course financial benefit as well.
No, I don't really care. I am a supporter of copyfree, but I can't make my wiki public domain, not without asking people to relicense their contribution.
Nonetheless, I am experimenting to see if it is true. It's only one sample. So far, I am not suffering any ill effects.
