Ah well that put a positive note on my morning coffee. I didn't know that.

But still wouldn't it be valuable to the bidders for Amazon to fix this? Or shouldn't Amazon value better targeting because relevant ads convince users to engage with the platform more? The people selling the coffee filters are still guaranteed my business, just not before 6 months. I always buy from the same seller too so it could be a good opportunity for a competitor to sneak in right at the 6 month mark and make a new repeat customer.

I guess the answer to that is probably "well the system works well enough elsewhere so that would just be hyper-optimization"
