> Facebook also offended a fair number of bereaved people with its Year in Review clips [...] The problem was that for some, these were pictures of dead loved ones."

There was a recent ad on FB from a maker of teapods that said something like "share a cup of tea with your dad". Unfortunately, that ad was shown to people whose fathers were dead or abusive. My dad died before FB so I've never had any account in my friends list that an algorithm could consider to be my father. I'd link to it but I genuinely have no idea how to link to a Facebook post. :-/
