> If it's such a superior product that people want despite the tradeoffs, why don't they just fund a company to create such a phone? Why doesn't anyone?

That wont solve the problem of carbon footprint this is trying to solve? There is still going to be iPhones and samsung phones of the world in EU. And people will buy it. Unless you want EU to go full autocratic and enforce people to use just 1 phone manufacturer!

Last 4 phones I had, 3 was replaced cos of old battery and 1 was due to broken display.

Imagine you not being able to replace the SMPS (Power) in your custom PC even though your ~$2000 worth of hardware which includes GPU, CPU and motherboard is working perfectly fine.
