On top of all the other factors there is one simple fact. She's been doubling and tripling her portfolio since 2014-2015 (that's when she supposedly started to grow it) despite no sales whatsoever until 2021. And you simply don't do this - as a domainer, businessman, investor - whatever - that's an extremely anti logical thing. She had to pay a million at least already in renewals until she started seriously ''selling'' (put it in brackets for purpose) something.
Imagine you don't sell anything for years (talking about large purchases obviously, considering size of her portfolio), not a single word domain (which cost millions in .com) and for years - would you go ahead and buy more 2- words, misspells, numbers? (I analyzed her portfolio once - there were lots of very weird and simply bad names). Would you? No, you wouldn't do this. No person in their mind would.
And if, let's say, you ''believe'' in tld (how she claimed) and still have some funds to burn - you probably would leave maybe a 1000 cool single-word names, and that's it, and you'll cut the rest and go diversify your portfolio (another thing she never did, and that's extremely weird approach of not buying .com or any other extention), which, amongst the other factors bring me to a simple conclusion -
you only go more and more and more into the only one tld constantly buying if you are really backed up, connected and associated with this tld by somehow, or ... if you are this tld.
