My wild guess would be they got in the ballpark of $0.25 an install.
Hint: It starts with $ and ends with $.
I do not object to this notion at all! For one thing, it's not my comparison, it's my co-worker's. Also, an "inversion" of the scale's sign would serve as a sharp and salient commentary on problems in our society.
The road to poor security is paved with indifference.
Hey Lenovo, can you install this root cert I made on your entire product line for me? I'll give you like $20 for it. It's at least better than Superfish - I promise not to include the private key with a trivially-crackable password in the install, so only I can intercept all secure communications by any of your customers, instead of anybody in the world.
They sell laptops. It's not a free service, I am the customer not the product. Did Lenovo have a pressing financial need for these extra pennies on the side? Really? How is that benefit vs risk calculation looking now?
