Dell, from the computer owner's perspective, does some negative things as well.
Did you know that if you buy a Dell computer, you can't sell it without Dell's permission? If Dell finds out you sold your computer, they will blacklist you, and not sell you any more new computers! I know this from personal experience (I have been blacklisted for many years).
Much of Dell's hardware is non-standard, so that if you need to replace a major component, such as a motherboard, for example, you have to buy it from Dell because a standard board won't fit the case. Nice, Dell, way to piss people off!
