That’s absolutely not true. Bluetooth has many “profiles” which define different capabilities. Here’s a list of them. These are all defined in the official bluetooth standards.
Maybe you were thinking of the “core specification” which defines the underlying protocol but doesn’t define the profiles? But that’s just the way they broke up the spec documents. The profiles are still official parts of bluetooth.
Apple’s proprietary extensions for audio are not part of any official specification though.
It’s certainly the one most likely to shank you if you step on it. Beyond that I’d rank it as the least space efficient plug. I honestly think it’s the worst design I’ve seen.
“But it has built in fuses”, I hear all the Brits say. This isn’t the advantage you think it is. Why not put the fuses in the actual appliance with all the other components where it makes more sense to put them?
If a comment is funny to the person giving it and offensive to the target it’s not a joke, it’s just bigotry.
There’s a reason why no-one bought IBM PS/2s. They were horrible value for money.
The real competition at the time was the thousands of other brands selling PCs. By that time IBM was plummeting in sales and other companies were selling most of the PCs. That’s where 95% of the market was.
