Lenovo is a company that you paid your money to to buy a laptop. It shouldn't come pre-infected with something that compromises your security and privacy.

They screwed up by denying there was problem in the first place. Which means they were defending both their decision to install Superfish as well as, by proxy, Superfish itself.

Thus they are seen to be either incompetent (can't trust them) or malicious (also can't trust them).

Also consumers never bought Superfish. They paid for a relatively expensive piece of hardware from Lenovo and got screwed. They are right to blame Lenovo for it.

Because Lenova is the one who took your hundreds to thousand+ dollars and in return compromised your experience (for what has to be pennies). And in this case it caused a serious security compromise?

"EVERY PC manufacturer bundles adware"

Crapware/bloatware and adware are very different things. Dell installs some bloatware crap that I can uninstall (and even that is, truly, unacceptable. Again, they can't make more than a dollar or two on that junk, yet they compromise the user experience), but they don't MITM my secure communications, or compromise my security.

This has nothing to do with Lenova being a Chinese company. Further, no one expects anything out of Superfish (some slimy adware company), but they do expect standards from Lenova.
