Drawing a thrown weapon isn't like using ammunition; it counts as your item interaction for the turn.
Hmm. I guess by RAW, that's true, but it hadn't occurred to me, and now that it does, I think I'm going to house-rule it out of my own campaigns. I see no reason to (effectively) punish Strength-throwers over Dex-shooters, and I don't see why it'd be harder (for instance) to grab a throwing axe off a bandoleer than it would be to yank an arrow out of a quiver.
Yep. Bows are for traditional fighter types, because they're proficient and they can make lots of attacks. Crossbows are for utility fighters (rogues and clerics) who only ever get one attack anyway, and generally aren't proficient in longbows.

One thing your article missed about the sling: It's the only ammunition weapon that is neither loading nor two-handed. You can fire multiple attacks while equipping a shield or leaving a hand free for ready spellcasting!
It amuses me that there are lots, and lots, and lots, of threads on various forums where people foam at the mouth "you can't load a hand crossbow one-handed" yet I think a sling would be harder to load one-handed. Also, rules-as-written, a level 20 fighter can fire a sling four times a round while only firing a hand crossbow once.
My experience with a sling is that it is not just point-and-shoot - it takes a few seconds to wind up to a good speed before you can loose the missile.
It is also a *lot* harder to learn to aim well with a sling than a hand crossbow, yet in the game the sling is simple and the crossbow martial.
On this point, I think it was pretty much standard back in the day for a javelin thrower to hold several javelins in his off-hand and pass them into his other hand for throwing. Would this type of action count as an item interaction?
That video is a far cry from showing that it is "easily accomplished". In fact, by the end he says that most slingers never used a sling, and even the skirmishers would 'run forward, fire, then run back to reload" If it was "easily accomplished" there would be no need to run back and forth.It's true that a sling requires a minimal amount of dexterity with a second hand to load, but it's easily accomplished even while holding a shield, as this guy demonstrates:
