Either I'm missing something, or this article clearly suggests, that pilots are using ILS for landing only in bad weather conditions. Which could lead to an assumption, that in perfectly clear weather they're landing always or nearly always in visual.

Even though I'm complete newbie to aviation, I was always sure, that ILS is used on every landing procedure, now matter, if weather conditions are good enough to do it visually. ILS landing seems to be faster, more precise and thus more safe and thus -- in my naive opinion -- should be use whenever it is available (i.e. whenever ILS is commisioned and operational).

What am I missing?
