The core WordPress software is amazing. The plugin developers and community are another story. I've had cases where WordPress plugins have unlisted dependencies, bundled plugins that completely alter the WordPress Dashboard, build systems that go against established WordPress software patterns, etc etc etc. The majority of the community seems to be fine with this as they treat it like self-hosted Squarespace (set it, forget it, don't need to learn programming, contract any programming that does need to happen as cheaply as possible).
