And I don't know, because I have about 60 minutes a week to think about this, and also good quantitative market analysis is really hard.
So whilst it may sound like a good reposte to go "wow, I bet you make so much money shorting!" knowing that I don't and can't, it's also facile. Because I don't mind if I'm right in 12, 24 or 60 months. Fwiw, I thought I'd be right in 12 months, 12 months ago. Oops. Good thing I didn't attempt to "make money" in an endeavor where the upside is 100% of your wager, and the downside theoretically infinite.
Mind you, this is a view that exists - a few large hedge funds and sell side firms currently hold negative positions/views on these companies.
However, the fact of the matter is, fewer people are willing to take that bet than the opposite view. So it is reasonable to state that view with care.
You might be right at the end of the day, but it is very much not obvious that this bet has not (or will not) pay off.
