Can I remove Modern Comments and revert back?
Send feedback to Microsoft to let them know what you think about the so-called modern comments; for instructions, see https://support.microsoft.com/en-us/office/how-do-i-give-feedback-on-microsoft-office-2b102d44-b43f-4dd2-9ff4-23cf144cfb11.
Microsoft's rationale about "posting" is mentioned in the support article at https://support.microsoft.com/en-us/office/using-modern-comments-in-word-edc6ae71-0a2d-49fe-8faa-986f1e48136a (which you may have seen already).
Finally, you should see an option to temporarily revert to the previous, more user-friendly interface at File > Options > General. Clear the check box next to "Enable modern comments."
I suspect that most experienced users of Word agree with your opinions. Some fellow Word MVPs have reported several shortcomings and limitations of the new "comment experience" to the Office team.
What you can do is post feedback via File > Feedback in Word.
