Let me present the case of Ubercart as a counterpoint. It was the upcoming, loved by many e-commerce system built on top of Drupal. When I first looked at it in 2008, it was still in alpha. But it looked like having solid devs and good community behind it. So I jumped on it, built my site around it and even developed custom modules for it. Fast forward to 2010. The project has forked and the main dev has gove over to develop the next generation of Drupal e-commerce system which is a completely separate project. It is only being developed for Drupal 7 and has no migration path from UC. I heard that someone from the original team is still continuing to work on Ubercart but the site has had no updates for about a year. To put it in perspective, this leaves me with 2 options. One is to live with the old UC (which still lacked a lot of stuff since it was pretty much work in progress) and keep investing further in developing on it while knowing that underlying platform is dead. Or I can jump over to Drupal Commerce which would mean I would need to move to Drupal 7 which would mean porting all the rest of my custom development (which has nothing to do with e-commerce part) over to D7 which I had no need to! For those who do not know, Drupal does not maintain backward compatibility between major version upgrades. Having said that, I don't have any gripes with UC devs. I have benefited from their hard work and thank them for that. I am just pointing out that even Drupal ecosystem is vulnerable to what the original article said.
