You can find a few counter examples but they never last because the commercial pressure is too high, the obvious example is Sony, are they still deploying rootkits? Lenovo is another example that has started cleaning up its act.

Would these companies change if their only source of funds was the malware? I don't think so.

lenovo is still bundling crap with their laptops. nothing has changed, they got rid of the specific thing that caused the outrage, that's all.
