Some people seem to want to argue that there is already CSAM in Bitcoin's blockchain. This is false. Bitcoin today does not support images at all - only arbitrary data up to 80 bytes (or 95 in the coinbase).
Exploits like "Inscriptions" work by _misinterpreting_ script code, and _bypassing_ existing policy rules. They are not actually storing images, but merely putting gibberish code on the chain, which they later themselves (not Bitcoin) _misinterpret_ as images.
This distinction is very real and relevant. If you don't differentiate between "data that can be misinterpreted to produce CSAM" and "data that correctly interpreted displays CSAM", then literally _all data_ is CSAM, with _no exceptions at all_. This tweet would be CSAM. Google's logo would be CSAM. Your phone's operating system would be CSAM. Literally anything _can_ be misinterpreted as CSAM.

Yep, educate them Luke!
Bitcoin does not intentionally support images, but intentions many times depart from reality. Unintentionally supporting arbitrary data, IS a way to support images, among other things. And yes, many arbitrary data storage solutions indirectly support images, including for sure a phone's OS, among other devices. And some images can fall into the CSAM category, thus being illegal. It seems unnecessary to force arguments to deny the obvious.
