So I take it you can't define "few" and can't prove how many miners there actually were.
I take it that you can't read. The information shown shows that Evan instamined roughly half of the Dash that was emitted during that time, and there were at most 100 other 'miners' using services such as amazon and microsoft. That's comparable to NXT's distribution of just avg '70' people. So yes, very few people mined during that time and I highly doubt each ec2 was a different person(I'm betting many of them were owned by Evan and co).
I didn't read the whole wall of text, just randomly clicked a link that said "nobody could compile". The proof of the claim was a link to a post, but the very next post was the guy admitting it was his own fault he couldn't compile, not Evan's:
Yeah, my bad, I botched the layover of the makefile on the update.
If the rest of the "proof" is as solid, it's not worth it to read further.
