Just bought a Lenovo laptop over the weekend for my wife. Sounds to me like it's no longer being installed on the laptops, but will check it to make sure Superfish isn't there.
What's worse though is that they apparently don't have any QA whatsoever since they pushed an update that made the device basically unusable (keywords: Nexus 7 2012 Android 5).
Not running crapware is theft, just like not watching commercials is theft. The only way they can afford to sell you a PC at those prices is by subsidizing their profit with crapware income. /s
Plus you need to have a separate OS license as well to make it work.
It's challenging because most people can't install an OS.
The software you will want from Lenovo is their System Updater which can be installed on a fresh (non-Lenovo) Windows install, and will let you install drivers and similar software (nothing is forced, all up to you).
The one thing you won't be able to install the various pieces of crapware, but that is a benefit.
