Germany's the richest EU country and doesn't hesitate to throw its weight around to get things done their way which is why many refer to the EU as having a German leadership and it's why many other EU countries are unhappy as some German policies are highly unpopular at EU level (supporting illegal mass migration, anti-nuclear "green" stance while burning gas and coal, long term pro-Russian stance, etc.), as are their politicians at EU level like Ursula who have a track record of incompetence and corruption yet are still in power.

That doesn't make Germany the leader of the EU and even less Europe. They play an way to important role but EU, gladly, doesn't allow defacto leaders

It still has way more influence than any other EU member and can push its internal agenda more easily.

And since it's also the biggest market in the EU, whatever quirky internal rules and regulations Germany has, get pretty much automatically carried out at EU level by any and all companies looking to do business in the EU.
