I agree!! And the smiley with its mouth open and the blood red color inside it looks bloody and gross. I don't know what they were thinking and why it is such a challenge for a company like Microsoft to revert these icons. Part of the problem is that most comments are finding their way into communities and where folks report issues they have to select category and the some people are entering under the emojis category and others under the Microsoft Teams category, and so on and because of the dispersion the number of votes gets diluted across many requests instead of accumulated. They have no idea how many thousands of us want this rolled back. I wonder if Microsoft's Marketing team knows how bad this is for their Brand?
I entered an issue, too: https://feedbackportal.microsoft.com/feedback/idea/39d837d7-6512-ed11-a81b-6045bd7d68ae . Maybe if they have enough issues raised and all of them are "up-voted", they'll get it. Maybe we all should flood them with issues and up-vote all of them.
