I can see how it may be more frictionless for you to use Google Docs, and how this may be less work for you than for example installing and running your own Etherpad. But I think it's too grand a statement to say that "You Don't Need Wordpress" because people that don't want to give up their online freedom still do.
Maybe that's what's upsetting people about this project, it's grandiose title that's dismissing another successful free blogging platform? While I fell kinda bad about defending anything PHP, WordPress does have a lot of extensions and your solution couldn't replace WooCommerce or WPForms.

For my blog that I mentioned in my top comment, I use Google Docs because I'm working with people that usually don't know Markdown (I'm interviewing e-commerce business owners).
I need it to be as easy as possible for them to get the written interview done. From my experience, a Google doc is the easiest way to do this, and it allows for very familiar features when I ask them for edits or provide feedback in-document.

This is just my experience.
