> I'm still baffled at how everyone considers these startups to be "underachieving"

Explaining that was the entire point of the article. Given that startups by definition need fast growth ('definition' being pg's definition, as explained in the article) and given that the growth of these startups has slowed dramatically, these startups are underachieving.

Maybe 'underperforming' would be a better word to use, since we're all familiar with that term as it relates to companies large and small.
