Nothing about the freedom of the software has to do with whether or not you compensate the authors for creating it.
If you take free software and never consider paying its developer for making it, despite them providing you freedom, choice, and a degree of trust in the software you can not have with proprietary code, then you are the kind of person to blame for why proprietary software is so rampant today.
For example, I donate $200 to the Document Foundation every year to match the cost of an annual subscription to Office 365 plus a 33% bonus for respecting my freedom.
Expecting open source doesn't mean I wouldn't pay for it. I co-founded a company that is fully open source, so I do understand that money needs to exchange hands to keep this industry flowing. I just believe in freely sharing ideas.
