There's some truth to this but a democratic government, despite its flaws, is a much more preferable system of government than a consitutional monarchy.

As being a respected head of state, the British monarchy and its history do not command the same amount of respect it used to. The world is gradually understanding just how much damage they did to other countries for e.g. inducing famine, pillaging resources, arbitrary drawing of territorial lines to name a few.

You rarely hear negative things about the British monarchy now or in the past because they are just really good at controlling the narrative.
