This is true. I've lived in the Bay Area since '05, and have met many people who were there since the 80's and 90's. Actually, I think most of them have left. But by the mid 2010's, many of them would comment on how unusual it was that the fog just wasn't rolling in anymore. One person I knew was sensitive to certain allergies that would become markedly worse without the fog. So she knew. It isn't just SF proper. Along the peninsula, on Highway 35, the fog used to be so thick you couldn't see more than 30 ft in front of you – maybe even 10 ft some days, and especially in the evening. I lived in those mountains around the 2006-2007 timeframe, and it was fun to drive down the 35 by memory (at least if you were an indestructible-feeling 20-something), since it wasn't possible to see down the road for any safe distance. Nowadays, there might be fog, but it's invariably "safe."
