That's not a question. That's a statement with a question mark at the end. Also, the statement ignores the fact that the parent comment asserted edits have no impact on demonitization, so even if it was correct it would be moot.
However, in this case, interpreting this as question rather than a statement leads us to see a question about the inner thoughts of the commenter, which clearly is not what was intended.
What I believe was intended was to make a statement that was to be understood as uncertain. However, the "I think" prefix is all that is necessary for that and the addition of a question mark just creates uncertainty about the it being interrogative/declarative.
