This is one reason Sony moved away from Qualcomm, in order to have truly wireless with Qualcomm's BT chips, the smartphone (or device) would need to use a high end Snapdragon SoC, either 845 or higher or the new 855, I do not recall. So this basically eliminates all iphones, ipods, walkmans from sony, and other media players. Sony did not want this, so they approached Mediatek/Airoha to have a truly wireless BT chip that worked with all devices and models.
I don't think Qualcomm wants to license out aptX, maybe they will change their minds in the future, who knows.
AAC has license fees, so this is maybe why it was dropped by some.

I'm not sure I understand what you're getting at. The snapdragon 845 and newer Soc's can utilize Qualcomm's TWS+ which is each bud connecting to the phone separately.
The Lypertek Tevi for example supports this if your phone has an 845 or newer chip, but if the phone you're using doesn't support this you can still use the Tevi in a master/slave configuration with any phone and still have aptx or AAC.
So, Sony could have still used a Qualcomm chip and still had aptx and AAC and be compatible with any phone.
If I'm understanding correctly, all true wireless with the exception of ones that support Qualcomm's TWS+ all work in a master/slave configuration where only one bud is connected to the phone, and the other channel is sent from one bud to the other.
