Standing On Priciple

Much has been made of late about the revival of switching to open source. Casting off the shackles of iTunes DRM and running naked in the fields of sweet, sweet Freedom!

So riddle me this, if you ditch proprietary desktop apps because you are taking a principled stand against the tyranny of closed source software or formats, are you also ditching Google web apps (search, mail, etc.)? Isn't Google's search algorithm is every bit as proprietary as Apple's iMovie? Yahoo web apps? Flickr? Exporting your data in an open format isn't or shouldn't be enough! The app must be Free (as in speech), right? Just like Wordpress. Oh, I remember the Great Movable Type exodus like it happened yesterday.

I know...I know. I'm just being an ass. We all have that line and it's in a different place for all of us. I would love to hear the reasoning behind why it's okay to use Google and not iMovie though (or mix and match any non-open source web app with a non-open source desktop app)...even if it is a sad statement as to what I find entertaining in terms of conversation.

Update: I should note that I'm not trying to mock people for taking this stand, just that it looks like there are rather large caveats about said stand.
