For the most part, yes.

In general, my doing something that I want to do for free is different (usually) from you asking me to do a job that you want done for free.

Now, of course, there can be exchanges that don't involve money changing hands. Perhaps part of the deal is that I get into a concert (or whatever) for free and that may be perfectly reasonable. I do attend events on media passes on the (implicit) condition I'll publish a story about some aspect of the event.
