Well then you're pretty well mistaken. There is zero reason for Apple to casually announce the Find My network via press release a week before introducing an almost meaningless commercial product in AirTags. Apple doesn't create products where they offer nothing unique to the existing market. The Find My network is their unique contribution. Anyone can make a tracker tag.
Plus, why would Apple care about making a measly amount of money off the tracker tag? This would be a such a bottom of the barrel product for them, needlessly harming the third parties for whom they just built the Find My network. For something so small in potential, they would waste the good will they purchase with the Find My network.
AirTags are real. They're just an in-house product, made for developing the Find My network. This much is pretty obvious now.
