What annoys me to no end is that I was Whatsapping with a local restaurant for food delivery during the lockdown and two days later, the owner pops up in my Facebook "suggested friends" list.
Or is it your confirmation bias where you expect people to distrust Facebook for the wrong reasons so that you can post that link?
Because funnily enough, I didn't place blame in my comment. I just pointed out my 'annoyance'. You, on the other hand, concluded something from that. Ironically.
What other reason for ‘annoyance’ could you have, other than assuming that the WhatsApp messages lead to the suggested friend, and thus you were annoyed that the data was (supposedly) shared? If you just also just thought it was a coincidence, what would you be annoyed about?
