I am a tech person and I have only maintained AMP is a blight. Anyone of us, with even a smidge of business sense could see what they were doing/going to do for quite some time. The people who argued for its benefits very much lacked perspective (or didn't care) outside of the immediate technical effects of speeding up mobile sites. People in tech are not particularly homogeneous in their opinions on a lot of these things and you probably saw a small slice of the various opinions.
