Could it be AMDs doing behind the scenes? I don't see the motivation for Lenovo here but I do see AMD asking vendors to do this to prevent OEM CPUs completing with retail CPUs.

The feature was implemented in 2017 the only vendors that are using it are lenovo and dell. With lenovo being the only one using it on lower tier cpus than epyc.

It's probably both of their fault. Lenovo wouldn't do it unless there was something in it for them. I wouldn't be surprised if they get a better deal from AMD on these CPUs for being locked to a specific board (killing off their ability to be used in the parts reseller market).

Dell have been vendor-locking their AMD CPUs the same way for a while now

Previously it was limited to EPYC chips (the huge server parts) but it's spread down the stack to Threadripper Pro (high end workstation) chips as well now

You misunderstood. This is about resale of base components. Go to ebay and look up 2-3 generations old Intel chips - super cheap from China. With this you wont find cheap AMD parts since they will be locked to Lenovo motherboards.

It makes sense for server security as discussed by the same source as the op https://www.servethehome.com/amd-psb-vendor-locks-epyc-cpus-...

I imagine its Lenovo asking for lower prices on Chinese market bound CPUs and AMD being super happy killing secondary market after seeing Intel server/workstation CPUs flooding out of Asia.
