there's plenty of ways to make a useful graph without giving exact numbers. and if he really didn't want to give information away to his customers, he'd not write the blog post in the first place.
Blog posts are marketing, he's driving traffic to his site with this blog. and his "facts" amount to squiggly lines. he doesn't deserve to get traffic from this.

Yes, the article could have been more useful. But the way to make that happen in the future isn't to bitch endlessly about people not doing enough free work for you. It's to thank them for the good you got out of it, and politely suggest next time that their article could be even more valuable if they did X.
