Anecdote time - I use Apple music and am generally happy with it. However, some time ago I started putting on the 'Sleep Sounds' playlist before going to bed. That's messed up my recommendations for my 'New Music Mix,' a more valuable feature for me. Even after disliking the 'Sleep Sounds' and specifying that it shouldn't recommend more music like it, my recommendations are still messed up. Makes one wonder to what extent in the age of 'AI' whether everyone is an edge-case in some form, particularly when (as you point out) context is a big mess.
I googled some info about a rival college football team. At some point Google decided I was a fan of that team an my news feeds was flooded with news about that team... and not the team I actually follow.
No amount of user input saying 'don't show me this' would make it go away for more than a month or two, and eventually I just stopped looking at google news and turned off the google news feed entirely in android...
Google news, whatever it does has entirely disconnected itself from most anything relevant to what I want, to the point that it is a negative experience using it compared to some random news site.
