Ad hominem much? The point is an issue with the declaration of will to pursue a contract. You can challenge that after the fact.

My girlfriend accidentally bought Minecraft because she wanted to check out whether she could pay via PayPal. There are no further confirmations. Also no refund possible even though she hasn’t even installed it once. If I could be bothered, I’d sue, but in Germany that wouldn’t financially make sense, even though it would not be a hard case at all
