Microsoft should have never killed MSN messenger. It still blows my mind that Microsoft went through evolution of so many chat apps only to be overtaken by Slack as the business chat app. Teams is good but the experience is still not great compared to Slack. Same on mobile. They had windows mobile evolved for so long, only to be overtaken by Android and iOS.
