In France Netflix acts as a limited 1-season preview to tease me into torrenting the full series. House of Cards only had season 1 when the 4th was out in the USA.
Could it be that it's because Netflix arrived late in France and by that time it had already sold the rights to broadcast House of Cards in France to some pay TV network? In Australia we had similar issues. If that's the case, the situation should "normalise" in a couple of years, since the rights are usually time-constrained.
That’s when Netflix was starting out, no? Do you get both seasons of Stranger Things for example? Initially they selling rights to shows much more than I think they do now.
