No. I need it to conduct business, and that's more important to me than posting or discussing controversial topics. People in China literally do not use email, so this is the only effective method to get things done (which I'm totally ok with!). This ban would be an absolute disaster for me, given that my entire rolodex are WeChat contacts, not email addresses.
I also feel for my friends who have family in China, and want to stay connected with them through a medium that is widely adopted.
There is a cultural standard that is just different in China when it comes to free speech, and it's hard for most people in the US to accept that.
