Disagree. There is risk that the process applied itself is wrong.
I've seen a lot of posts from you in factor threads but I've always struggled to figure out what your specific argument is.
I got some time now, let me see if I can explain. First, I was responding in between breaks, so I am not sure if Vineviz meant something different, I have to go back and check.
Second, about your specific questions:

Do you believe that factors do not explain returns?
I think they do. They are helpful for explaining returns post-fact.

Do you believe that factors may explain returns, but won't have any premium going forwards?
The word premium itself is misleading. It can be negative or positive. Calling something that can be negative as a "premium" is a twist on the whole thing. Even if the idea was originated by FF, I think it was popularized by industry hungry for selling products. I do not think it is possible to systemically capture an excess return premium in any reliable manner over any reliable period of time. It may not even happen in your lifetime. I reject the argument that all these factors are to be viewed same as equity risk premium. I think there is a huge difference, much of it has to do with behavioral aspects of it. I believe market ranks ERP higher than any other factor premium. I cannot prove it, but nether can other side disprove it.
I do not know for sure whether there will be premium from investing in SCV or not, no one does, and to repeat myself, I don't think it's the same as thinking there will be an equity premium going forward. I see no reason why the market should reward you for investing in a company that is about to go bankrupt, for all you know this company will go bankrupt and you'll lose everything. Now, the theory goes that if you select a portfolio of thousands of such stocks then a few winners will come out of it, because as the academics like to call they "surprised" the market (instead of the word mispricing). The idea is that such few winners win so big to earn an excess premium. So, goes the theory behind SCV. Do you see why I find it hard to believe that this phenomenon will happen reliably in my lifetime? Possible, but should I do it. Bogle says, even if you tilt limit yourself to 15%, I think that's reasonable.

Do you believe that factor funds are improperly constructed? Do you believe that factor funds are being improperly sold to investors who expect a guaranteed short term premium out of them?
Yes, and no - to both. Some, not all are improperly constructed. Those that are constructed properly sticks to the fundamentals, others have added on several things, including the AQR long/short strategies are found to have flaws, which even they cannot figure out. Professionally, I am a technology leader, I build complex systems with many moving parts, my approach to building systems is to build them with only the needed moving parts, just enough to get to the desired goals, anymore and I am adding more complexity and more errors that needs to be chased down. Same goes for factor products, more algorithms, more room for errors.
Some companies take advantage of it, for instance I saw the other day a fund advertised as "high yield factor" fund or "floating rate factor" fund. What is stopping someone to claim they discovered another factor that was proven in backtests, then market it, if they are slick at marketing they could make big bucks. Investor beware in this regard is my motto.
