I think a lot of hardware companies are still in the "smart" transition phase. In the sense that they've only been offering a product line with GUI driven software component for the past ~5 years.
Which means the larger companies* are probably on schedule for development to start slowing because of technical debt. And therefore solving that (modern development practices and open source involvement!) will become a competive advantage.
* Sadly, the smaller companies will probably always be hacked-together-MVP stacks on top of whatever release they started dev on
