No. If I am not happy with the conditions I just don't buy, that's all. I don't see your point.

I said that I don't see justifications for these conditions, but still, this is his product, he can sell it with the conditions he wants.

To me it's just as weird as the car seller who wants to sell me a red car, but doesn't want me to paint it in blue.

PS : This is denial of alienation concept, and it's quite incompatible with the very concept of selling. Such a denial of alienation requires the use of law and public force to monitor and check every single commercial transaction not only during actual transaction, but also after transaction and during the whole lifetime of the product. This is awful and vain waste of resource and money.into juridical complexity. I doubt this is something society really benefit from, and therefore I would personally avoid and discourage it.
