The EU Commission is elected by the European Parliament into power and can be fired by the European Parliament anytime. Pretty much standard for governments in parliamentary democracies. If that isn’t democratic, you don’t consider parliamentary democracies democratic in general?

The Commission is unique in the way that it alone can initiate legislation but the right to initiative is routinely blown out of proportion. In most countries this power of their parliaments is mostly facade nowadays, because the governments there are actually drafting legislation and if needed parliaments just rubber stamp the initiative. This is further watered down because both Council and Parliament can propose legislative initiative to the Commission, which the Commission usually follows through. While the Commission can try to prevent legal initiative, it can do little to prevent the amending of current legislative proposals in the works. This is actually relevant for Stop Killing Games, if you followed the news of the initiative.
