Ironically, I’m part of a Chabad community, but I don’t use Chabad for the mentioned things. I used to use Chabad for Zmanim, but after they updated their site a few times it got annoying. Also, you can’t see Magein Avraham Zmanim on Chabad obviously.
To the nay sayers, Chabad is actually the most popular source for this information, so LB isn’t too far off in thinking most people would go to them for it. I think LB is referring to the extremists who deny the good Chabad has done. You can be non-Chabad and disagree 100% with their shita without being anti-Chabad.
