Dude. Please.
Alec was almost 100% spot on. Normal divers are who look at his usually very helpful channel (normal divers also look at the Lake Hickory Scuba channel, the other very helpful channel on YouTube; it's a shame there aren't more), and normal divers use a yellow octopus. He stated that using a standard configuration is safer than not doing so, which is usually true (and, in fact is the mantra of tec divers, who just use a different standard). Again, yellow octopus is the standard config. He's not aiming at tec divers, but at rec divers. Calling it "Tech Tips" means it's about the equipment normal divers use, as opposed to fish ID or some such thing, not that it's somehow about tec diving. He should have been more accurate in describing long hose use, but his ultimate point was solid. Do you see dive shops renting gear in other configurations? Not very often, because it would be begging for a very well deserved lawsuit when someone gets hurt.
By the way, calling him a doper, or incoherent, or other things, isn't a logical argument. Nor is saying things like that everyone has a yellow octopus only because that's what's sold--you can just put a period at "octopus," as the next phrase is just pointless. He's a bit goofy, but that's OK.
On another note, I thank the people who responded to my questions about the rationale for primary donate. However, most of those reasons had to do with mixed gases, knobs rolling on ceilings, twin tank configurations, and so forth. None of that has anything at all to do with normal divers. So, while tec gear configuration might be good for the very few, most of those rationales don't apply to rec diving. Just the "let's be nice and give people a clean reg" type of rationale applies.
