This is a dumb investigation IMO. Microsoft bundle all of their work/business/student programs in a bundle for - get this - workplaces and businesses and students. Having to exclude Teams arbitrarily doesn’t make sense. Should they also have to unbundle Excel because alternatives exist? Powerpoint too? Should they not be allowed to bundle anything? Customers are free to still use slack etc if they want to, but Teams belongs in the bundle with their other products because it integrates directly with all of those products.
