It isn't fear, I just think it a dumb design, and they do appear to have reliability problems due to it. It's not like chain driven overhead cams are a big mystery to anyone, including Ford. There is always a price to complexity.
The early ones had some issues. Even then as a percentage of total population they were low, and became quite rare after 2005.
