It's a reasonable expectation that a framework with more users will have more documentation, more examples, more contributions from the community, etc. While I agree that a developer should choose based on what will make them most productive and happy, popularity is still an important factor.

When comparing 2 or more frameworks or libraries to use, I always check out the github repo and look at the number of stars. I don't see a problem with this article pointing out that this metric may not be the best indicator of usage.
