Businesses don't care about opensource, and they already use standard electronics, just not modular, because modules are expensive. E.g. many Haier/Candy mostly use esp32 microcontrollers, led displays don't even need modules, lcd displays use usually one of few standards, etc. A cheap microwave costs 50euros, a washing machine 200, that's retail price with a 5year warranty, sometimes even with delivery, there is no place for modules that noone will actually use.
