Are you referring to the author specifically? Or a specific hypocritical person you know? If you're making a general statement about groups of online people you might be falling for the group attribution error[1], where the characteristics of an individual are assumed to be reflective of the whole group.

In any case, two things can be simultaneously true:

1. Writing code is not the bottleneck, as in we can develop features faster than they can be deployed. 2. It's annoying and disruptive to be interrupted when doing work that requires deep focus.
