As you said, we don’t know. What we do know is that Apple has a vested interest in Apple Music subscribers and AirPlay. It doesn’t make a lot of financial sense for them to deny software solutions ( if they allowed it in the past..unless they have a security issue with new firmware). Apple wasn’t telling people they were working on certification… that was Wiim. Like I said, it’s a non issue for me, so I don’t care either way, but until we hear specifics from both sides, we won’t have the full story. All I know is that I have tons of Apple AirPlay devices from everyone Belkin, Yamaha, Marantz, Denon, and even Wiim. Hard to come to the conclusion that Apple is the problem without all the facts.
We do know
a little more than that, even though only from WiiM's perspective. Their statements are pretty clear now.
Originally they expected the Ultra to become AirPlay certified, just as every other device they made so far. However, the certification was
not completed before introduction to the market. This came as a surprise to WiiM.
At this point they decided to remove all references to AirPlay from their marketing material and sell the Ultra, anyway. Sadly, not all retailers did the same. Also, at this point in time most potential customers did believe that a future firmware update would certainly enable AirPlay. It's not clear if WiiM knew better by then, but I expect they were still negotiating with Apple.
The final statement from WiiM was that the Ultra as is cannot support AirPlay because it doesn't have the MFi chip. That says two things: 1. They didn't expect to need the hardware chip (ask yourself why) and 2. Apple told them they need it (ask yourself when).
I come to the conclusion that it's far more likely, Apple did change something in their certification process or in the way they're dealing with WiiM then just WiiM "fucked up" as a friendly fellow member liked to call it.
No matter what Apple's interest may or may not be, WiiM has absolutely
no advantage from (and thus no interest in) not supporting AirPlay in their top of the line streamer, only.
WiiM made themselves vulnerable by starting mass production prior to receiving the certification. Apple explicitly tells participants in the MFi programme not to do that. This was their mistake ...
