That's not quite the point tho, is it?
Renault messed him about for at least the last 12 months. He's got the right to play hardball as per the terms of the contract. This time last year it they were playing Palmer and Magnussen off having signed Hulk, until Magnussen told them to do one and went to Haas which worked out pretty well all considered.
The point I was making is that, as he doesn't need the money, I don't quite understand why he's going.
Of course Renault want shot of him so they can slot Sainz in but he's obviously got a contract. Usually drivers can be bought off but, as he doesn't need the money, he'd have been far better off sticking with it in the hope of doing well in the remaining races and raising his stock for whatever he chooses to try next.
I guess he's been offered enough money to outweigh any perceived advantage from racing to the end of the season.
Either way, good riddance. As I've said before, I think he was actually lucky with his reliability issues as they masked his general hopelessness. He's crashed or otherwise screwed up in half the races this year, failed to out-qualify Hulkenberg even once and scored one whole point.
