This doesn't work if the entire market has converged, which it has. It's very similar to telling people who don't want a smart TV to "just buy something else", because that limits you to used options.

Used is great, but it means you aren't participating in the market and manufacturers will not account for you. In other words, you literally cannot "vote with your wallet". This is coincidentally also a big reason why monopolies and duopolies are bad.
