My assessment as well. QAnon did nothing to help, and everything to harm, Trump’s efforts.
There is no such thing as QAnon. Its one or the other. IMO Its a Psyops campaign of how the deep state is going to be taken down if its anything, not on or for protecting the President. Think of it more like Nostrodemus predictions than anything else. Cryptic and vague. I can’t see how it was harmful because, it was always 100% pro Trump. It all boils down to perception. You either like him or hate him, no middle ground.
It was never 100% pro-Trump, and “QAnon” delivered particularly harmful messages: e.g., Trust Sessions, Trust Barr, Trust the plan.
