Apple not allowing 3rd parties use of their proprietary technology is not the entirety of the DoJ’s argument. For example, their claims about Messages and Apple Watch are about support Apple hasn’t built, not about what they prevent 3rd parties from building.
I don't believe third party accessories support the compass-style precision finding though.
Hang onto your old RF-transparent wallet, because RFID blocking has become a standard bullet-point feature they all have to have now.
It was nice-enough case for my phone and it primarily kept the phone from getting beat up by other pocket-stuff that would happen in a workday. But it also had two compartments: One was shielded all around by conductive fabric and this made a fairly good Faraday cage, and for the other one layer of that conductive fabric would be pushed aside so that the Faraday cage was incomplete (and thus largely non-functional).
It gave me a choice, and that choice worked well.
I think I paid $3 for it back in the day from DealExtreme (which was a lot like Temu is today, except shipping normally took months instead of days or weeks).
Is choice not a thing in modern RFID-blocking wallets?
[0: There was a time when my company felt it was useful to track people with their company-provided cell phones. I didn't mind that during the workday, so much, but we were also encouraged to use these as our personal phones if we chose to, and strongly encouraged to keep them with us 24/7 so we would be reachable.
And I didn't mind being reachable most or all of the time and I certainly enjoyed not having my own cell phone bill back then, but I did not like being tracked 24/7: Sometimes, I wanted to do my own private shit on my own time without being snooped on.
I could tell the tracking app to exit, and that did work, but doing so sent a notification to my completely stupid, abusive manager -- who would variously either call to ask why I did that, or just silently turn it back on remotely (which the system permitted).
And I did not (and do not) think that, as a professional, I needed to excuse my choice to have privacy at any given time. (Given my own role in the company I had access to this tracking data as well, but I'm not the abusive type.)
So, the solution was simple: Normally, the phone was in the non-shielded part of the case. And when I dropped it into the completely-surrounded Faraday portion instead, the phone just simply dropped off and silently stopped providing updates.
This worked 100%, and while I refer to them as separate compartments to aid in functional clarity, the design of this case didn't really take up any more space than any other phone-case would have.]
There's like three different places I put my phone in different areas of the house, and only one where I put my wallet and keys as soon as I enter.
I would like an airtag to put on my bike or laptop or other high value item to track it if stolen, but I'm not about to buy Apple stuff.
(Also: AFAIK the "large"--not really, in comparison to the AirTag + adapter, lol--Tile Pro variants have a noticeably longer range than AirTags.) Honestly, the only thing, to me, missing from Tile is the direction arrow finder, which is certainly useful, and yet... the speakers on the Tile are much much better so it just doesn't matter so much?
(BTW: it is extremely stupid that that arrow only works in two directions. I waste so much time following the arrow only to realize I need to go upstairs -- I live in a two story apartment with a bedroom and an office above my kitchen and living room: it isn't larger than my friends's apartments, but it is really nice having two floors -- that I am only doing because the sound isn't loud enough on AirTags.)
Frankly, the whole argument for AirTags being inherently better is merely that they have a "bigger network", but for most of my objects I am not scavenging around town looking for then, nor am I ever going to be chasing some thief around the city in my car looking to steal it back, hoping to catch up to them before they disable or throw out the tracker... that vigilante justice idea associated with this product category is just a crazy pipe dream.
Instead, I am pretty much always just trying to figure out which pair of pants I left my wallet in today, or on which shelf I left my keys: I would actually be much happier with a purely local product that only responded to encrypted pings from my personal phone and only even did that when I actively ask it to (as despite using both Tile and AirTags for years now the "you left your item behind" notifications have only happened before I myself noticed once or twice in a way which was helpful... it just doesn't ping often enough, with either product, to be maximally useful).
And looking at the replies to this, I have learned AirTags are actually missing what is to me a glorious feature of Tile: that I can push a button on my keys and find my phone in reverse. I hadn't noticed this lack before as I am only using AirTags in large objects I don't keep on my person (which makes their notifications really annoying as the UI fails to eat old ones even when I walk back to my object... this seems very fixable), but I don't want to have to buy an Apple Watch just to have a way to find my phone :/.
