I think some of these are unfair criticisms, because they are things that can be trivially changed. E.g. disabling evil mode or changing the theme are one-line modifications in the Doom config. After all, any opinionated Emacs distro has to make some choices otherwise there would be little point in anyone using one.

For me the issues with Doom are (a) the complexity as a whole that it introduces, and (b) so many things are already installed/configured that you end up using them without any real "under the hood" understanding which is so essential for customisation.
