Really quick that leads to not being able to buy anything though.

Sony has done a bunch of evil things (deleting paid media, hiding rootkits in music CDs). Apple abuses their monopoly to force using their web browser and extort a 30% cut of all purchases. Every car manufacturer is tracking every car they sell and selling that data. Retailers are tracking store visits using everything from face recognition to MAC addresses on cell phones.

Boycotting can only do so much. We need regulations to protect people and steep fines for violating them.
