They aren't indicators for market's price, they are indicators for general market state - they show how much activity from users is happening at the given time. There's no denying that they correlate with big price movements caused by big masses of people.
You are wrong about Trump's tweets - they didn't cause any reaction from Google trends, in fact the latest spike happened in the end of June, which is exactly the time when Bitcoin surged.
