If you share an AMP page it will indeed link to Google's CDN but if you click it it immediately redirects to the full article on desktop:

The full URL is still part of the shared link, so not much of a value has been lost, but the gain (speed boost) still outperforms this "inconvenience".

I don't really feel the hatred against AMP, it works as intended and for me as an end user that's all that matters.
