"Freediving" originated with the pearl and sponge divers of ancient times. It wasn't called "snorkeling". Actually, it was called "skin diving" in the earlier part of the 20th century. Today, snorkeling does not mean you are going to depth of 100+ ft, etc. The idea that there is no distinction is nonsensical. Go on a typical snorkel boat and say "Hey, everyone, alright follow me! We're going to go down to 100 ft and look around" See what everyone says about that, LOL.
Back in the late '50"s and '60's, as I remember, skin diving was the term mostly used, and free diving, snorkeling and SCUBA were included in the term. Skin diving and free diving were used to differentiate from a hard hat diver and anyone using surface supplied air. SCUBA had to have specific equipment so it was differentiated from skin diving earlier and free diving was used by few including competitive freedivers, who later turned it into one word (similar to the acronym SCUBA being changed to the noun scuba). Skin diving went out of use when Skin Diving Magazine folded. Who knows, it might come back in a different form. The only annoyance I have, besides using SCUBA as a noun, is that snorkeling is an activity that is now defined as floating on the surface with with a snorkel and vest to keep one on the surface, rather than the larger group of activities it can be.

It gives no date of origin for freediving being used as a word rather than two. It also excludes snorkelers who can do the same activities with a snorkel.
It's all quite confusing, and makes communication difficult, when words change in meaning.
