From the wired.com article:
Two Apple customers have filed a lawsuit accusing the Cupertino, California, company of committing violations of computer-fraud laws by recording location data of iPhone and iPad customers.
Vikram Ajjampur, an iPhone customer in Florida, and William Devito, a New York iPad customer, filed the suit in federal court April 22 in Tampa, Florida.
I honestly don't know how this is going to turn out, and I'm not probably the best person to make a judgement based on how often I check-in using similar services. However the point here if everything is as the plaintiff's case says, Apple lied about collecting and/or using that data for their own benefit. If it can then be proven that Apple somehow profited from this data (collecting without the users' consent)... whoa.

Update: Apple-using Foreign Gov'ts want to know why they were being tracked too.
