This is just my opinion, but I don't think it's fair to blame Roku because your TV is setup in a way that won't work with it. Roku is going above and beyond offering a free extender. You can buy your own if you need one for your TV.
I couldn't disagree more. Roku should include the extender with every
stick like Amazon does (or at least they did when I got my Fire stick).
AV equipment classically doesn't come with cables, even those types of products that always needs cables to work.
Why would a Stick based product come with a cable that only a small portion of people would need? Why not expect those people to purchase the cable only if they need it? Why blame the manufacturer when it's the person's responsibility to order a product that will work their their TV?
