The six-time F1 champion was then given a five-second penalty during the race itself for an incident involving Red Bull's Alex Albon in the closing stages, resulting in him being classified fourth after crossing the line second behind team-mate Valtteri Bottas.
All this followed Red Bull's protest on Friday against Mercedes' DAS system, one that was eventually thrown out by the stewards.
Wolff said: "I thought the protest on Friday was actually fair play, but not on Sunday. Coming back on Sunday morning, turning around a decision from yesterday, if you have new evidence, that is what the rules allow, you have to take that on the chin.
"I think that in the race - putting all these things together - in the race the penalty was too harsh.
"But coming back to your question - the gloves are off."
"I think the reliability issues here come from the kerbs. It's a great track, but if you run the kerbs too wide, which is within the rules, you damage your suspension," added Wolff.
"So it is a permanent evaluation of the driver, how quickly you want to go, how much you want to ride the kerbs. By their nature they want to go as quick as possible and if you do that you risk suspension damage or vibrations to the car that can break it."
