uh if you've got a keylogger on your system, clipboard access is not that far away

oof.. i'm gonna go with slightly above average luck

IMO I don't think "convenience" is a fair argument. If Windows did not allow their users to install another client, that would be one thing. But just pre-installing something on their own OS isn't grounds for any complaint whatsoever. You don't get to complain that Company XYZ makes a product A and bundles it with their product B and makes it more convenient for users lmao. Users have the means to install any client they want.
