I have been following the controversy around AMP fairly closely. A lot of people whose opinions I respect are against AMP generally, although I still cautiously think AMP is generally a good thing. At least, it is in my view clearly better than Facebook Instant Articles.
So if AMP is Google’s response to Facebook, I am in favour of it. Facebook’s interest is clearly to keep people in the Facebook ecosystem. AMP may give Google some a bit of control over content, but it still keeps it fundamentally of the web. At least you don’t have to use Google to use AMP.
However, AMP for Email seems far more obviously bad. Not least because, as this article points out, it appears to be a solution looking for a problem.
There may be cause to be wary of Google’s intentions after all.
