That’s great for you, but try to convince one other person who’s not already in your headspace they should not buy any more TVs. That’s almost an impossible ask. Like telling someone not to get an Android or iPhone because of the data collection. Geeks like us can put up with these inconveniences but we’re a very small minority.
People are still going to get the product unless there’s a truly viable alternative available. Until we see a new standard whose goal is to specifically target replacing HDMI in this context, there’s not really any way to suggest people “vote with their wallet” on something as common as HDMI.
