Websites have one-sided, unfair contracts. Apps access phone features that let them spy on you. You're not reading the fine print. But you should.
Used for sharing photos on Twitter, Twitpic has one-sided terms that any self-respecting artist would despise.
Twitpic takes credit for your photos, the company keeps your deleted images and you can't sue the company after a year. You still own the copyright to the work, but what's a copyright if you can't take credit?
The provisions are so bad that the consumer protection project Terms of Service Didn't Read gave it the worst possible grade.
