Light Phone dudes, if your whole thing is going to be future-proofing and "planned obsolescence remains an outrage to us," maybe don't stick III at the end of your product's name.
What is the connection? You don't always have to buy the latest of anything, certainly not the latest Light Phone. And as I'm sure you read, "We have no plans to stop producing or supporting the Light Phone II."
If they serve different needs and purposes, then name them based on the distinct goals. On the other hand, if you get into a habit of regularly releasing new models that are strictly better than their predecessors, you're setting your internal incentives up towards encouraging your customers to upgrade, and that way lies planned obsolescence, despite your current best intentions.
