Don't worry, wasn't taken as a attack or insult or anything. I just wanted to clear up some issues in the post.

But just to confirm, I do personally use Composer for everything and disable core updates, plugins, etc. But that's a personal choice and not one that using Composer forces on you.

I find myself defensive against attitudes like this in the WordPress world because most people (including WP core devs) are so against new tools and technologies. It's for that reason that I usually find posts like this more harmful than helpful (which I know isn't your intention).
