I'd be really happy with products having to be labeled with:

1. Final date the manufacturer will provide firmware updates & security updates 2. If the manufacturer will support open source alternative firmware & security updates. 3. If there are any subscription fees (and how much) to get firmware updates & security updates.

Issue #1 is a big deal: I've purchased equipment, new in the box, after the mfg had discontinued support. I've also ran into issues with devices where updates required a subscription. I'd love a little disclosure.
