because there is nothing, the court acknowledged that he wasn't part of anything but they decided to sentence him, the reason is he spoke to Valbuena. They were never going to let him go free after 6 years, they had to find something and anything to sentence him.
The French Football federation doesn't care because they know this case and they know very well Benzema. it seems people still don't know why Benzema wasn't selected in French National Team for the past 6 years. Deschamps had personal issues with Benzema and that is THE only reason why he wasn't back in the NT, not the valbuena thing.
