Nobody should not be forced to create AMP sites in order to appear at the top of search results.
Mozilla opposes the implementation of the Web Packaging specification [2], which includes Signed HTTP Exchanges, mainly because it can be used to take away control from publishers over the distribution of content.

If you're from the US, please write to your representatives and let them know about AMP.
