"Women have to appropriate the language of men to get on in the world"
Firstly, women shouldn't need to change their language to "get on in the world". I think the "Just Not Sorry" feature is a good idea, it helps you to change the "weak" sentences which is good, but I think this should be a feature that pops up for ALL sexes. It's not always about the gender. It's more to do with the status of the person. Less ladies will get offended if the feature comes up for men, and some weaker men will appreciate the help if they're unsure and need to look like a strong independent man.
A further point I would like to raise is if this is an apology email, obviously you're going to undermine yourself if you bought the wrong biscuits for your colleges, or walked in the wrong toilets on your boss taking a leisurely pee. You might be a newbie. You're not expected to know what you're doing straight away. If this feature doesn't let you use words like "sorry", it won't be a very sincere email and you might get fired.
