Take Cycling: ANT+ Radio is the defacto standard for cyclists sensors. Everything from power meters to heart rate monitors use ANT+ because of its incredible battery life, ease of connectivity, and low latency. Yes there are BLE versions of everything, but they absolutely suck batteries. I change the batteries in my speed/cadence sensors maybe once every 18 months. Apple proved it can already reach these battery lifetimes with AirTags.
Apple typically enters a market and destroys competitor markets by introducing a new protocol and only supporting the new standard, fragmenting the market, then holding out until competitors run out of cash, at which point they can do whatever they way.
They're often quite successful with this, although they recently had to admit defeat with USB-C.
