It's hard for me to understand why the fact that Google's autoreply exists is objectionable. If you don't like the response, don't use it. Nobody is the poorer. For those looking at a more nuanced critique, the Baffler published this:

I think it captures the effects of autoreply more accurately, at least the effects of a writer living outside of Silicon Valley.

While Google's suggestions may often be off-base, they are also often reasonable, but they may shift your register a little. That is, they are designed for people using email to make quick decisions and respond in a professional way.
