The Feds are coming, and I hope they keep going and going until there isn't a single product or service left that dares dictate what you can do after the transaction is complete.
I've been rolling the idea around that perhaps if a product is encumbered by a subscription then it's not a first sale and the product counts as inventory. And gets taxed as such.
When I buy something I must pay sales tax to the government. Later, if it turns out I never owned it and ownership is revoked, can I get the sales tax back?
