Re: iOS "interoperability"?
If Tile makes their trackers compatible with the new Apple/Google standard (no idea if that requires new hardware or if they can do a software update to what they have) then you no longer need anyone else to adopt the Tile app.
The reason Airtags worked better than Tile the moment they were introduced is because they were supported in the OS, so everyone's iPhone helped track the location of every Airtag. A solution that requires people have to be running a third party app was never going to work as well no matter how popular that third party solution was. Heck even if Facebook had introduced a tracker the number of people leaving the Facebook app running and giving it permission to use bluetooth would have made it much less successful than Airtag.
The combined Apple/Google standard improved things for Airtags, especially in places where iPhones are rare (third world) and but more importantly for you allowed everyone's trackers like Tile's to compete on even footing - they all have access the same worldwide tracking network consisting of all the iPhones and Androids. So if you like Tile better than this made your Tile WAY better than it used to be, without having to hope that more people will run Tile's app (and leave it running, a lot of people close down apps on their phone when they aren't using them)
