And that isn't a veered-off attack, content free and waste of bandwidth?
You asked a straight question in order to promote some discussion on whether or not google is PFI. I think you got that. The fact that people don't think that it is doesn't invalidate their opinion.
Seriously, to me you sound really p*55ed off at google for some reason. By all means vent, but don't take it personally if nobody posts what you want to read.
Back on topic, you asked a very specific question - "Is google PFI" to which, IMO, the answer is a straightforward "No". However, if you had asked "Can I perform well in googles SERPS in a competitive arena for free" then I would say the answer is "probably not - go buy that PR7 link to get you started".
I think the reason the thread veered a little off-topic is because people felt that they couldn't answer your original question in such a simplified way (i.e. just "no") without explaining their thoughts on it, most of which enevitably relate to positioning in the SERPS, not just getting into the index.
I don't know anyone who's ever bought a link just to get into google. I know plenty who've bought links to improve their SERPS postioning though.
