In Ch. 7, the Harry-and-Draco conversation needs to be toned down even further because multiple parents have announced their intention to have their children read this fanfic – and I know that revision is going to be controversial, but Draco’s current conversation is also a little out-of-character by the standards of the Draco in later chapters.

This is an explicit statement that the concern about kids reading MoR is what is prompting the revision, with minor considerations about Draco's character being secondary.
