iFixit noted yesterday, "Though the bill is strong and should make repairs more available for everyone, it allows manufacturers to continue to engage in parts pairing, a practice by which they limit repairs with software blocks. They can also combine parts into expensive assemblies, which makes repairs more expensive."

Similarly doubt there's any way to legislate against the dismal engineering that tempts a failure avalanche like the Ford F150 taillight horrorshow I posted a few days ago.

This has been the issue with similar laws for automotive parts. Technically by law they have to make parts available for 10 years iirc. However, they don't have to make them affordable.
