Developers always have to answer to someone. That might be a client who's buying bespoke software, or a customer who bought something off the shelf, or a user who uses something that's made internally within a company. If there's someone who uses the application then there's someone who you have to justify things to. No developer who writes code for money can just push out changes without worrying about breaking things.

The view that people who build and sell products can go faster and have less stress than people who write code for other people is nonsense. The pressures basically are the same; they're just from different groups of people.
