So I'm going to focus on this last part, and again, not trying to be argumentative, just trying to make sure we are on the same page.
WoTC
cannot reorganize or go public. Yes, "companies" do things all the time, but specificity is not just the soul of narrative, it's also a requirement for things like the SEC and various legal restrictions.
The point that I made (and reiterated by
@mamba ) is that WoTC isn't going to do anything. I'm not going into the finer points of LLCs, but I think we can be reasonably certain that it's got a single member, if you know what I mean. Hasbro could do things, but not WoTC. We have to start by understanding that point. We can refer to WoTC, and it has a reason (la la, taxes, la la, corporate shield, etc.), but Hasbro is the entity for practical purposes.
So everything has to be examined in terms of what Hasbro would do. They could spin off "WoTC" (referring to various ways to do that) but this is not some panacea; this incurs costs.
Again, not wanting to get dragged into this. But the idea that Hasbro could simply "get rid of the bad stuff, and keep the awesome stuff," sounds great in theory, but there's a reason that they aren't doing that other than stupidity. They may choose to pursue that in the future, but even assuming, arguendo, that every thing works out, you have to remember this-
A standalone "NuHasbro" that is called WoTC will have additional issues caused by the transaction, and will, if anything, be further driven to monetize the brand.
TLDR; there is no such thing as a free lunch, and it is difficult to see a future that doesn't include "MOAR MONETIZATION" of D&D and MtG and so on. Because, you know, capitalism.
