To your question, is it "ok," I couldn't provide the answer as I don't own the copyright.
My statement was that I wish we lived in a world without copyright. The rules would be very different, and thus we would act and compete differently. As is, brand is an important asset for a company. I think you know all this.
I also think your argument is a bit sophomoric and I find it obnoxious that you are calling out my employer's name.
Or are you also advocating for changes to trademark law?

Google copying Yahoo's front page code? Okay, that'll be in the news and everyone will have a good laugh.
Some Joe Schmoe Web Developer lifting CSS/HTML from an unknown client to sell to an unknown client? Eh, not so much. This probably happens often and goes undetected.
Edit: I'm obviously not serious.
