But the problem is that people unaware of the facts see it, buy it as truth

… as planned.

I agree. I don't think artistic license should allow you to use real names, real places, real times and then fabricate what happened. If someone wants to make up a story to make a point or express a moral view then fine, make up a story, but don't knowingly conflate historical events with fiction. Some license with dialog and scenes in portraying private conversations and locations while recreating the past in understandable, but changing facts is not. "Based on a true story" should mean that is true to the facts to the extent possible, otherwise change the names, places and times and call it what it is - fiction.
