It also seems quite arrogant to make a drastic change and impose it on users–if WordPress is supposed to be a community, this is an autocratic and completely inappropriate gesture. If support is later withdrawn for the classic editor plugin–that would be holding people hostage who have put in a great deal of effort to learn WordPress and may be maintaining sites using it.
I absolutely hate this editor too. It is fine as a plugin for people who like it, but as the standard default editor–terrible decision.
