I tend to agree. On one level, you could say it's a satire and even a mockery to VCs in general (which I found hilarious when I found out who Tagger was).

However, in real life I think this would be a polite response. It might read like bullshit but it's quite fair to see he's trying to make these points. Everything else not in the email (e.g. why does the VC not want to invest) would be speculation.
