Since events like this famous case, where Walmart outed a teenage girl pregnancy, it's well-known they mix in some "weird" or irrelevant things to give a sense of plausible deniability. "oh, pregger testers, haha, how weird they can be <nervous laughter>".
This was Target not Walmart and I say that not to nitpick but rather highlight that arguably Walmart is somewhat an upper tier tech company.
If this is what Target does in 2012, Amazon in 2020 not only inserts plausible deniability to optimize for lack-of-creepiness factor. They're probably running AI bots on forums and social media injecting seamless product placement in commentary you see in your browser.
