My sense from this discussion is that the opinions being expressed by those opposed to crate training puppies are not professional trainers. Breeding an animal for 20 years will provide a lot of insight and experience with a breed and with dogs, I have much respect for that accumulated knowledge, but, not to sound rude, that does not make that person a certified or licensed trainer. We keep babies in a crib to keep them safe; we do the same for puppies. Just to be certain we're on the same page, I'm not advocating that any dog, puppy or adult, be crated all day long. I agree with not crating at night once the pup is potty/crate trained (the two work together well).
I have learned from several certified dog training professionals who use modern positive-reinforcement techniques. This includes Brenda Aloff, Michelle Lennon, and I've reviewed content from others including Zak George, and Ken McCann. They all say something very similar to what Michelle states in this video about common misperceptions regarding crate training puppies (and she also states her credentials).

Being a scientist myself with a Ph.D., I'm a skeptic of unproven claims from un-credentialed sources regardless of experience. Indeed, those who claim they are right based on experience raises red flags for me. I favor advice from those with the most recent and demonstrated evidence-based knowledge. John Maynard Keynes was reported to have said in response to a person questioning why he changed his view on on a policy matter, "Sir, when I encounter new facts, I change my mind. What do you do?" (That wasn't what he actually said, but it makes the point.)
The techniques I learned regarding crate training have worked, so I'm rather skeptical that Basenjis are so different than other dogs in this regard.
But as someone wrote above, "the bottom line is what works for you."
