Thinking more about it I am not sure that there is a conflict there.
If I use Apache to run my web site I am still within the ideals GPL.
My PHP application does not need to be GPL and if I write a special module for Apache that does not need to be GPL.
If I try to make money off selling Apache with my module or PHP then I run afoul of the intent of the GPL.
Your comparison of Office/OOffice/Gdocs is interesting but you could just as easily substitute Gdocs for www.theweathernetwork.com or Linkedin.
The question should be: Are you locked into a proprietary data format?
The real issue is; can I take my data with some application and can I move it to some other application?
And that has little to do with any of the copyleft schemes.
Once upon a time I developed a bunch of IBCS software for a project I was working on but the project was going nowhere so I released it to some Linux kernel folks with the request that I get "some credit".
I am also not sure that this is a religious fight.
Religious fights usually involve people killing each other.
I often say there are only 2 true evils in the world: Politics and Religion.
Its the reason we kill each other en-mass.
