[Cerowrt-devel] [Bloat] Off-topic: What to Make of the U.K.’s New Code of Practice on Internet-of-Things Security

[Dave Taht]

There should probably be a list for political issues somewhere.

I am liking various proposals for improving device security like this
and the german router thing (https://www.ccc.de/de/updates/2018/risikorouter
) but missing from all these requirements is

"the right to repair"


" The code also asks manufacturers to disclose a minimum timeline for
 software updates and makes provisions for devices or components that
 cannot be updated through software, noting that the manufacturer can
 replace them—in fact, under U.K. law they must repair or replace faulty
 products for 6 years."

oh, I so wish we had that in the US. But what qualifies as faulty?
