Regardless of whether you agree with the rule or not, it maybe too stringent in some people's opinion, it is a rule set by the NFL. The NFL goes to great lengths, having meetings with these players, especially the rookies, on what they can and cannot do. He absolutely knew the rule and if he didn't or was confused it wasn't bc he was not informed. I hate it for him, but either way this is on him. At least publicly, he is taking responsibility (he really doesn't have a choice). Take the punishment and move. Calvin Ridley has done it and based on his comments he is better on the other side.
