Put differently: Both companies want to make ethical devices. That already implies a non-profit-first philosophy. Just one company focuses on ethical for the end-user, and one for the producing side. Both have a passion for their focus, but would probably admit that the other is valuable.
And also, it’s already hard enough to reach that ONE goal. How much hard work Nager-IT put into the effort to create an ethical mouse. It’s just a mouse! But a start.
In theory, collaboration could work. But maybe with Nager-IT there is less conflict of interest than with FairPhone. They could bundle a fair mouse with their laptops, giving attention to that noble cause. And with the supply-chain knowledge, they could go for conflict free PCBs for the Librems. That’d be nice.
