I totally understand the issue raised by this article.

But I have a problem: I like AMP because it is so fast!

Publishers have done this to themselves by loading up simple web pages with hundreds of scripts that slow it down to almost unusable levels.

Maybe if publishers stopped doing that, then you could start criticizing AMP.

"Some of my clients will ask me what to do with those messages. I will tell them to delete them. Ignore Google’s nudging, pay no heed."

And then your clients will be unhappy with the traffic results. Are you going to also tell your clients the drawbacks?
