I have two Yale Zwave locks that are at least 11 years old and still kicking. The key factor to this is the non reliance on the cloud.

Zigbee, Zwave, Esphome and other non-cloud will always work longer than any cloud based solution that is at risk of being shutdown, use a outdated or no longer available app, become a subscription, etc.

I agree with you that they should be required by law to open their code and unlock the devices but I doubt this will happen any time soon.
