> Maybe you are the exception but I find that 99.99% of the people who use the "it's open source so I can modify it" argument never so much as look at the code let alone consider making modifications.

I like to live in a country with free speech even if I am not a journalist. For the same reason, even if I personally am not modifying much, I want the software I use to be libre. Nothing about price.
