Vendors should be entitled to withdraw support on particular hardware, but they shouldn't be allowed to brick the service as a result 'just because'. All it needs is a TOS/EULA update prompt advising that viewers with X hardware are on their own as of now. I'd be willing to bet this denial of service practice originates in kickback discussions between TV manufacturers and streamers.

It strikes me as another case where corporate can inculcate learned helplessness in the customer by having him think disallowing and withdrawing support for are indivisible.
