Non American here, and also not a lawyer, but I’m curious what the correlation is between consumer rights (or lack of) and the relative cost of the product. This is somewhat different to buying a cheaply manufactured product and it unsurprisingly falling to bits - though in many jurisdictions there are even basic rights for that situation, the price is irrelevent. Someone elsewhere in chat has suggested suing in small claims for the cost of the product, due to Roku intentionally bricking their own product unless the rightful owner (is the purchaser even the owner?) agrees to certain terms, even though OP purchased it in good faith. If a straight up refund is not available during a straight forward opt OUT option, we have a very unfair situation for the rightful owner of this product. Needless to say opting out should be as straight forward as opting in. Your suggestions is that if a product is of or below a certain price you must bend over and gratefully accept the corporation you paid money to, then inserting anything they like up your rear end. In my opinion your thesis is not price based as this is a common practice unfortunately in the consumer (and enterprise for that matter) tech industry where we have had shiny brand even expensive products initially sensitively torpedoed up our various orifices, only for brand HQ weeks later to press a button which flicks open hidden blades in the torpedo. No one wants or deserves this. The question is what recourse is there in OP’s jurisdiction.

I may be misunderstanding you if actually you mean that any tech corp can do such a thing at any time that you have paid for. In which case we agree. But it’s far from ideal and shouldn't be accepted.
