I think one of the things that people are missing with regard to aspects of the OSR is that there is a real "DIY" or "indie" strain to it. It has largely been about hobbyists publishing for other hobbyists with a decent amount of skepticism towards "professional" designers and any centralization of the movement.
I think this indie strain came from about a half decade of pre-3e fans hoping that the professionals would "do it right" and then being repeatedly disappointed with the effort - from 3e to Hackmaster to Necromancer to C&C - and deciding to just do it themselves. I actually think there's a pretty big divide in the pre-3e D&D community, albeit a subtle one, between those who still yearn for "official recognition" and those who've said "F--- it, we can do it better than they would anyway."
Thus, regarding what some others had posited abot a hypothetical 4e that was closer in spirit to 1e... Really, by 2008, that ship had already sailed as far as any of the producers of OSR materials were concerned. What WotC or really any mainstream producer of D&D-ish materials was doing at that point was so far off the radar, they were going to be putting out their own materials no matter what, audience or no.
Now, what 4e has done is it's put the wind in the sails in terms of audience for the OSR products. Those fed up with 3e but disappointed in 4e had one more place to look. So, while the OSR'ers had been there for 3 or 4 years already producing tons of materials (one example: 30 adventure modules for OSRIC alone had come out prior to 4e being published), a lot of people only discovered them when they decided to see what else was out there after 4e came out.
That is probably the best summary so far.
But, the OSR blogosphere is in part about remembering, touching back to the past, reviving the good old days, thinking what things would have been like if such and such did not happen, shedding the baggage that has come from following every new gaming trend...
I think there is a word for all this...
