It is open for me to use as I please. And I don't want to destroy their business. I can understand your ideological drive, but in reality it doesn't matter until you behave unethically and steal their intellectual property. Do you want that?
If you are sure that what you please is and always will be in line with what their company pleases, then I suppose so. Ideology has nothing to do with it. Nor does "unethically and steal their intellectual property" have anything to do with it- they can choose whatever license they want for their intellectual property and I can ethically choose not to use it. Unless your idea of "ethics" is for force me to use their intellectual property and agree to their license?
I mean I can go around calling C a functional programming language because it functions and I can build functioning programs with it... but that's not what the word means in anyone's discourse besides yours. I mean I support your freedom of speech, but also mine in saying your usage is disingenuous.
