For enterprise products the obvious 'large customers' to avoid are companies like Google and Facebook. They operate at such enormous scale that the problems you see there are unlikely to pop up in normal corporate use. If the article had mentioned these I would agree completely.

In my last company we had one particularly large customer that really put us on the map. It was grindingly hard to get things to work but fortunately they had a problem they really needed solved and just enough patience to let us solve the teething problems of new software. Once we had them as a reference it made a huge difference both in terms of product quality as well as validation of the company.
