Neither MS nor Apple has the best track record of building full-featured utility tools (which is why there are thousands of incredibly useful 3rd-party utility applications). I wish end-users would understand that giving them a choice is more important than forcing them to use only OS-provided functionality. You aren't required to use anything that you don't like. The fact that you are complaining about a non-problem is odd. Lastly, incremental improvements generally come from outside the OS. If FF ends up adding something novel/interesting to their emoji picker, the major OS's will probably adopt it at some point. That would never happen in your world, where only the biggest companies get to innovate.
