Will the addition of proprietary software in distros hurt free software?

I found an interesting article today on the Linux Magazine site.  Christopher Smart talks about proprietary software being offered by Canonical, and utilizing it within Ubuntu.  This article point brings to light some very good questions and I am sure can be seen by both sides.  Those who are die hard, free software evangelists will not care for what Canonical is trying to accomplish.  While those who feel that proprietary software does have a place in Linux, will be opening their wallets to install software like Photoshop right into their distros.

Give the article a read and let us know how you feel.  Are you on the side of keeping all software within your distro open and free, or will you be installing some proprietary applications into your distro?
