Agree and disagree. It's not pointless, it's principled, and Stallman has this way of being right in the long term, so we ignore him at our peril.
However, for Linux to be a 100% replacement for Windows or OS X, we have to use to non-free software for some things. You could always choose not to do those things, as Stallman does, and sometimes I'm tempted given how little real utility movies and whatnot have in my life, but for Linux and all the free software it brings to make headway with the general public, non-free software is a necessary evil.
It's a tradeoff, both sides have pros and cons, gotta know them, and make an informed choice.
