Basically the French new outlets are some of the most subsidized on the planet.
Just to give you some quick figures, in 2010, the French government gave news outlets 1.8B euros in subsidies and in 2012 another 1.2B euros. There is no mention of the subsidies in the years after that but there is no reason to think that these would have shrunk significantly.
That's not even mentioning the special tax breaks that journalists get and the fact that most news outlets are staffed by union members.
Knowing that most unions are leaning left politically, it is fair to say that the coverage of the news by these outlets will be tainted by their political ideology. It's just human nature.
All of this to say that in light of all this, it is best to treat any French news outlet as basically an arm of the government that will never go against the interests of the their real owners, the politicians, unions and the billionaires.
Le Monde is but one of these outlets but nevertheless they take the money just like the other ones.
I want news about France, from abroad. I take what I can get.
I also have the Washington Post, The Economist, Nikkei, BBC, NYT, etc. and I'm sure you have plenty to say about them.
At the end, the goal is to have as many different sources and make your own opinions from their analysis.
