I agree with the above comments on the misuse of the word evil. Critiquing Microsoft vs Apple, or OSX, Windows, and Linux is ultimately fairly futile given that each provides very different usability to different customer bases. Having used computers running all three systems, I would say that they are all very good and useful at what they do. Apple provides a very simple, user friendly, highly compatible interface which is quite stable. Linux gives amazing access to everything, and in that regard is great for people who know what they are doing - coders, web designers and the like - there is a massive amount of freedom, but for people unfamiliar to the platform there is a steep learning curve, and there is more work to have devices integrate. Windows sits between the two, offering a good amount of flexibility and access to the core systems, but still an accessible user interface. It does have it's security, stability, and bloatware issues though.
Regarding the 'evil' side of things, both Apple and Microsoft have some quite ruthless and sometimes ethically questionable business tactics, but this is different from evil, and not that different from any number of multinational corporations. It just seems like Apple is moving in a direction that fans of Apple don't like (myself included), and therefore undeservedly earns the 'evil empire' badge.
