I started my career using Slack. Growing more senior, I couldn't help but notice Microsoft Teams popping up everywhere. IMO Slack is the better chat app, and Teams could be annoying - so I did some research to figure out why Teams just kept popping up, and I couldn't avoid it at work anymore.
I really thought this was obvious by now. If the data wasn't being scraped and analysed somewhere how would the categorisation of 'Purchases' work as well as all those payment reminders?
