Creatine is a health fad? No other supplement has been this widely-used for such a long time. It was considered safe and effective when I started using it 30 years ago. The benefits are/were well established, the mechanisms well-known, the safety is impeccable. If anything, it's the most well-established supplement on the market - the exact opposite of a fad!
My point is that creatine has had significant attention on it for decades. OP perceives an increase in attention but that's just a reflection of their knowledge (Baader–Meinhof effect)
