Nobody would complaining about Apple creating their own radio chips (which they seem to plan for 5G/6G). Apple creating their own standard protocols is an issue though.
I fixated on Apple because they're often picked on for taking the highway, but on the other hand what's the point doing otherwise? What's a common ground if it's just a pipe dream?
Breaking compatibility with that ecosystem out of spite is not conducive to getting adoption for a better product.
Now, of course, multiple nines of uptime would be very nice to have (and open up new use-cases), but 2-3 nines is still a lot better than 0.
You're arguing that it's not enough to make a correct implementation, but that it's also important to break compatibility with incorrect implementations.
I'm arguing that a better implementation that is compatible with current protocols is strictly better than a better implementation that is not Bluetooth-compatible.
If you make a piece of hardware that is good (e.g. doesn't randomly crash and need to be rebooted by the kernel), why is it a bad thing for it to try to connect to some flaky BT headset?
