Yes, but that doesn't change the point. The fact that MSFT has been able to build a product as good as slack is an anomaly. (and they apparently didnt succeed on the video/audio part as you said). Usually big corp like MSFT are not able to build an equivalent technology to someone else. Look at Google who tried in so many fields and never succeed, except mayble Hangout compared to zoom. So I agree with you on that. Nevertheless we know that the product is not that important. If all slack/zoom customers are migrated to Teams over night. The Teams product will keep most of its new users and will have a value for an acquisition, not because of its product, but because of its users. So even though I disagree that MSFT could build the chat application itself, I agree with OP that what is bought is not linked to the actual product
