I am probably the first guy who accepted his salary in pizza, juice, detergent, gas, and cinema tickets, got my paycheck last week, filled the gas tank, done some shopping, and just now I've reserved some seats for tomorrow. Since I bought 2 years ago some monero, am I the first to get a wage in monero?

There are 3-4 sentences about it, everything else in the article spends time talking about something else. The article looks more like something to market a service (bit4you) than real news. Great marketing...
The fact that they had to mention with whom he exchanged his coins is clear this was a publicity stunt, and btw:
Comme pour tout investissement financier, il faut faire ses choix avec énormément de précaution. Personnellement, je peux me permettre de prendre cette décision parce que je suis un privilégié et que j'ai pu mettre de l'argent de côté. Soyons clairs, je ne conseille à personne de se verser tout son salaire en bitcoin. Je conseille plutôt aux gens qui ont une petite épargne de placer de petites sommes en cryptomonnaies, 50 euros par exemple, pour commencer."
Let's be clear, I do not advise anyone to pay their entire salary in bitcoin.
It's good for Bitcoin's publicity and reputation, but I wonder what he'll do then. Can he afford to hodl all of his salary?
He said in the same interview he is rich enough to afford to lose all that and live without his salary for a year.
