If I remember correctly, Apple was supposed to openly accept and encourage others to leverage their network and make more “AirTag” capable devices.

Yes, because they get a commission for every device registered on the network.

In the join process, there is a key that is shared only for developers who paid the fee - which is why it's not really trivial to create an AirTag clone without dumping the Apple AirTag flash

A quick search on Amazon shows a number of generic trackers compatible with “Find My”. In fact, the one on my dog’s collar is one of these.
