Restrictions

I’m always happy for a friend when they start a job at Apple — but I’m also sad when it means they have to stop their community activities: no more podcasting and blogging, developer meetup organizing, presenting at conferences, writing side-project apps, contributing to open-source things.Brent Simmons

Those sort of restrictions is one of the reasons why I don't want to have a "job", i.e. be an employee.
