Isn't this a bit of a no-op for Lenovo specifically? I've been using Lenovo-made laptops for years, and never had trouble with DIY repairs - replacing keyboards, screens, batteries, adding RAM, etc. Their devices are pretty modular and DIY-friendly.
I wish they made charging plugs easier to replace, as these inevitably get damaged after 1-2 years, but that's really the only complaint I can think of. Is the situation different for other device types, or are they just trying to score an easy (if deserved) PR win?
