I'd say it was the other way around, MAP is an attempt at avoiding the stigma of pedophile, while CSAM is saying "pornography can be an entirely acceptable, positive, consensual thing, but that's not what 'pornography' involving children is, it's evidence of abuse or exploitation or..."
The term CSAM was adopted in the UK following outrage over the "Gary Glitter Effect" - soaring offence rates driven by news of people caught downloading images of unspeakable abuse crimes getting mild sentences for mere child porn.
This is why many feel strongly about defending the term "CSAM" from those who seek to dilute it to cover e.g. mild Grok-style child porn.
The UK Govt. has announced plans to define CSAM in law.
Only people who are involved in CSAM arguments on the internet know what CSAM means. Ask some random person on the street if they know what CSAM means. Then ask them if they know what child porn means.

I'm pretty sure you can add all the Governments, police depts and online safety organisations who use this term and rely upon it. Do include the 196 countries which depend on the Interpol CSAM database.
I fear you could be correct.
