Companies don’t necessarily use the superior standard, maybe you’re too young to have known or you don’t remember the time when each cellphone brand had their own plug and sometimes had a different plug for different phones…
Heck, the car charging ports are a perfect example, the government could have stepped in and imposed a standard in the early days of EVs, instead it had to wait nearly two decades for manufacturers to agree with brands using one of multiple standards for their car and now we’ll end up with charging stations that will be borderline useless in a couple of years because no one will be carrying a bunch of adapters just in case they try to charge somewhere with the wrong plug for their car and if the stations are updated then it’s still a whole lot of waste for the landfills and owners of older cars will need to carry adapters with them so they’re able to keep charging their car.
