Europe
I feel like this is a non-story. He does have a degree, and that it's no longer offered doesn't change anything.
According to other sources he only did one year and then dropped out. Not sure what a "Masters 1" is.
Usually after the back, you go to university, study three years L1, L2, L3 to get a License (otherwise you have education credits) and then 2 years (M1, M2) to get a Master, same note for the credits. If you dropped out after M1, you don't have a master and it seems to be illegal according to another post on the French Fediverse.
Hmm, reporting isn't what it used to be. The French would have probably caught on immediately. If this Stack Exchange is correct, it's definitely a story.
My apologies, my friend.
Fun fact I came across this on other media and was barely able to find any info on Google about it. I had to open Duck (Bing) which suddenly showed many results. So there is definitely some search engine surpression going on.
But it says the French government website retracted his degree so the story seems to check out.
Well I used ddg for my query so Stack was the first, best, and most clear answer. Which is surprising for obvious reasons.
