Maybe you should learn that these things are not as easily removed from each other as you imply.

Outlook == Exchange == O365; in the same way Gmail == Web & Service.

Complaints about the ecosystem of products (that incentivise their use and in some cases aggressively lock other tools out!) are all valid when complaining about an ecosystem.

Only pedantry need delineate them from each other, they're inextricably linked.

Outlook is not equal to Exchange. One can use other mail clients if they choose to do so (such as Apple Mail...).

Outlook also comes in a few different varieties which are oddly not the same.

have you ever worked in any company that uses exchange that does not also (pretty much) mandate outlook?
