I would try to see this from Evan's perspective. Its easy to find next to useless Sales people, its harder to find a good customer. Evan is a busy guy and said please don't waste my time with a Sales call this is only for your own benefit and then got something else.
And I don't want you Sales people poking around in my SaaS setup or in my data.
In the comments he posts another interaction with a sales-person. Read his second reply... I'd be happy losing him too. (As a business owner I understand how we get spam like this all the time, and I almost always ignore it if it is clearly not targeted. If someone goes out of their way to list some real reasons why they like my company though, I would try to be a little nicer)
