I don't know WHAT you people are smoking. The use of Teams at my company was so successful that IT leadership partnered with Microsoft reps to relaunch the product so that it could be even MORE successful. I don't know about you, but my favorite part is the forced clearing of chat history after 24 hours, and I really appreciate that Microsoft has become so successful by giving job-justifying IT managers at Fortune-sized companies such fine-grained "security" controls over how their product is used internally.
