Such things depends normaly on the Hotel standards. I had a lot of such things during my last trip to Portugal only 1,5 weeks ago: I had postcards, diffrent paper, envelopes... aaand free wifi/wlan service.
An example: In Germany you need a "Korrespondenzmappe" (which is exactly the thing you see on the picture) if you want a 4 or 5 star classification for your hotel.

Maybe they simply dropped the standard or the french classification has other rules.
