I'll be honest -- as a professional copyeditor, I hate this so much that, when I heard about the details of it from colleagues who'd already had it rolled out to them, I temporarily turned off updates on my account so that I could avoid getting it. I have some clients who require fast turnarounds on projects that require a lot of comments, and I can't afford to be slowed down right now by having to "post" every single one of my comments, let alone all this other nonsense. For goodness' sake, did you beta test this with ANYONE in the publishing industry?
Please make this an option that can be turned off or on as the user desires. I suppose it's possible that someone, somewhere might desperately want their process in commenting on a document to be slowed down (for some reason?), or desperately wants Word to work exactly like a Google Doc, but not a single professional editor I know (and, for the record, I'm the administrator of a professional organization of 400+ editors who basically all use Word and specifically the comment function on a daily basis...) wants this. I will not be turning updates back on my account until I hear some of these issues have been resolved, and, believe me, I'm savvy enough about cybersecurity that that is not a step I take lightly. But it was this or have my work as a small business owner ground down.
