I have only seen the Google side, just a single time when one of my Chipolos threw an alert on my passenger's Samsung.
My Chipolo certainly still works.
There are [cheap] tags being sold that are compatible with both Apple Find My and Google's Find Hub. I would rather have a dual-network device than Apple's improved model.
Would it be so difficult for Apple to put a hole in the Airtag so it could be directly attached to a keychain?
Here is an example of dual-network tags:

Do the Apple/Google "multi-tags" support the UWB precision finding from the phones?
Seems like apple is licensing usage of their Bluetooth protocol/scheme via the "MFi program".

Yes. It is surprisingly a near impossible engineering challenge at the levels Apple hardware is being done. Have you even considered the wear and tear that a mere hole in an ABS plastic molded detail would be subjected to over the lifespan of...several years?
(Just kidding, obviously they just want to upsell their customers with extremely overpriced accessories.)
Do these tags need to be configured on both networks to support both protocols? If I own an Android device and configure it there, will Apple devices still find the tag? How does that work?
