This ^ All the grocery stores in my area have them and it has yet to be an issue.
Also, not sure if you know this, but apparently if you have the Crappy Tire app, you can get the tags to flash/blink if you're looking for a product. Not sure how exactly it works on the customer's end, but my mum was telling me about it lol
I worked in a Walmart on the overnight shift (cleaning, separate company) when they rolled them out 3+ years ago here in Canada. They've honestly become the norm in grocery stores and other large stores here. If some company was going to be sleazy about them, it probably would've happened already (Loblaws, I'm looking at you).
I straight up asked why they were being installed, and it's two-fold. One, they can save money cause now they don't have to pay staff to go around and change the little paper tags, which takes an absurd amount of manpower and is easy to fuck up. And two, they can all be changed over to a barcode/QR code during inventory, which speeds up the whole process. I'll be the last person to defend corpos, especially Walmart, but I don't think this one was done with the intentions of directly fucking over the customer.
