It's your choice to work for those people.

Somehow, using open source as my primary platform for almost everything I do for work - for the last 20 years - has been pretty good for my career.

For me, having an open source phone is a smart choice. It means I'll be able to make the phone do things which are useful to me.

A closed phone doesn't offer that. The iPhone was shiny, but I couldn't see the point in getting one. Don't see how I'd find it useful - most of the apps I want to run are open source. Especially the productivity apps - which is sort of the point of a device like this, isn't it?
