I've spent plenty of time in my career building stupid things. While I'd prefer to build non-stupid things, as long as I'm getting paid well for it, I will happily build your stupid thing. If you get hung up on needing more control over what you're building, you actually have a few other options:

1. Take on a hobby in your free time.

2. Work for a different company, where developers have more of a stake and help define the product (there are few but they exist).

3. Moving into a "product management" role where you're defining features and requirements, etc.

4. Put your ass on the line and gamble on starting your own company.
