The Contract between TESLA and the purchaser is not the law, it governs the relationship between the two parties. The law, in this case, is actually clear cut, as the sale of a motor vehicle is not prohibited. Maybe Tesla can argue a breach of contract here. But for this forum, I would suggest this is irrelevant.
From my point of view, it is highly impractical to adopt a policy that any breach of a tesla contract has ramifications for discussions in this forum. You have to censor any discussion that revolves around the potential breach of any tesla contract, terms of use of the Tesla website, and so on.
Better would be to either move the post to a trading subforum or just to ignore the post.
A fair point could otherwise be made why other potential breaches of tesla's rights are accepted, and this one is not. All discussions around AliExpress accessories that potentially breach tesla Copyrights such as the use of the Tesla Logo etc. would equally breach teslas terms. After all, Tesla includes the tesla logos and other items in which it holds a Trademark/copyright and explicitly states that it reserves its rights in relation that these.
