Here's what I think. WOTC hired whoever they thought would benefit them the most in a combination of marketing, design, legal etc. It definitely looks right and good to have more women on their team especially in an environment where tech companies are constantly coming under fire for their stats on women. I have no problem with that given todays environment. There's a lot of reasons to bump a woman to the top of the list even if her expertise in her direct area of hire may not be quite as impressive as someone elses. Anyways we can speculate endlessly on why, and maybe she was hired solely based on merit, but I honestly don't care either way because it's fine they hired whoever they felt would give their company the most success for whatever reasons those were.
The issue I have is a bit broader. It's that we have gotten to the point where diversity (something outside an employees control) is often touted as more important than meritocracy (the one thing they can control). That's the root cause of people questioning many women and minorities that get hired for high and important positions. If it makes such good business sense to hire such people (as I believe it does for the reasons I outlined above) then it opens up many doubts about whether it was actually because of merit or because of sex or race.
It's socio-political-legal push for diversity in the workplace that is causing the doubts about merit. I do believe in a diverse workplace, but even moreso I believe in a merit based workplace. Diversity is great but never at the expense of merit.
You may very well be genuine in your use of 'meritocracy' but be aware that the meritocracy argument has become a favorite tactic of the alt-right in defending white supremacy. What is merit? Well, if you are measuring the things that the dominant socio-demographic group has has the most access to, then guess who is going to have the most merit? It's a self-perpetuating definition of merit.
Again, maybe that's not what you were thinking. I'm just saying that the meritocracy argument has become a euphemism, and is suspect.

In other words, the fact that she is a woman brings nothing to the table other than external optics. Because "merit" would be: RPG publishing experience, deep knowledge of complex rule systems, DMing skill, etc.
What that doesn't leave room for is that the people doing the hiring may have a very different definition of merit. They may have said, "Gosh, we have a ton of expertise about mechanics and adventure writing and game publishing, but for years we've been lacking A, B, and C, and we would put out much better products, and maybe evolve the genre as a whole, if we could bring in some new ideas and new points of view."
The world is full of examples where far-sighted leaders brought in "unqualified" outsiders, much to the consternation of their short-sighted underlings, who then started a revolution.
Example: Jony Ives had never designed a computer before he started consulting to Apple. I'm sure a bunch of people who
had designed computers grumbled about this.
So, yeah, anyway, I'm all for meritocracy as well. But merit can easily be defined too narrowly, and sometimes it is done so intentionally or subconsciously in order to restrict access.
