I'm not sure I agree. Yes, standardization is a good thing and AGPL is the "known evil", but having read it I do think that it is a very very complex piece of text - personally I'd go so far as to say that it is close to incomprehensible and would prefer pretty much anything else.
But even aside from that the sheer number of companies that point blank ban AGPL licensed software from being used in their stack could be used as an indicator as well. Though this may be due to the common misunderstanding that it is a viral license, which just goes back to my prior point on it not being clearly worded.
I won't even mention alternatives, I'm sure they all have issues, it is a complex topic, but if it were up to me the AGPL would not be my first license choice.
