So is the US president (Electoral College), the UK PM (Parliament) etc etc, yet you never hear complaints here from the same types.
Their opposition is ideological, democracy is just an excuse because their true views would be too unsavory to say out loud.
> So is the US president (Electoral College)
It has never happened, but if there once would be enough faithless electors to swing the election (choosing a different president than what people voted for) it would be a huge scandal and it would be widely condemned as undemocratic.
The criticism is about accountability, not whether the system is democratic.
The UK pm and the POTUS are both ultimately accountable through elections. In the UK, a general election can change the government. In the US, people vote specifically for presidential electors, even if it’s through the Electoral College.
The EU commission is different. People don’t vote for commissioners or the president, and they can’t vote them out in the same direct way.
In the US the President explicitly does not represent the people. It is the President of the States and only the States vote for President. Until the 20th century people weren't even involved in selecting who their State voted for.
Many people are confused by the fact that only States can vote for President. The most a person's vote can do is provide input into their State's votes for President.
