@hankg Why only 10 years?

There should be no limited time-frame for devices to receive security updates - you should be able to just install GNU on the device or a version of Android like Replicant and receive bug fixes updates with no end date - as really the computing community just keeps fixing bugs on an ongoing basis unless there's proprietary software preventing such updates.

If big manufacturers were to stop carrying out criminal acts such would easily be possible, but noooooo.
