Caffeine is universally bad not coffee.
I would disagree with that. Few things are universally bad.
In addition it speeds up the metabolism in a way which would create more free radicals, and this according to some lines of thinking would accelerate ageing.
Not necessarily. I would not want to make such declarations without extensive research.
Caffeine doesn't seem to be worth the risk even if a person doesn't get sick from it.
That is your perception but I think you miss the point of the article. Whatever you think of caffeine it is safe to take as part of coffee.
