Why can't an index fund compute and track their own objective index, thus ignoring any distortion introduced by the Nasdaq?

They don't target something else because they wouldn't be an index fund, that's just a passive fund with their own published strategy. Those exist but aren't as popular, the appeal of index funds is that you're just getting "the market" and "the market" is measured by the index. Public indexes are supposed to be lower-cost and less manipulable, but that was before they got large enough to "wag the dog," which is the ultimate point of the article.
Because when I buy QQQ expect it to track the Nasdaq-100, not something else.
Vast majority of index funds do not track NASDAQ 100.
This is the detail I'd really like to know more about
The top 3 most popular index fund ETFs track S&P500, which doesn't really pull this kind of shenanigan. Only QQQ tracks the NASDAQ 100 and it's in 5th place by assets under management.
You should probably read a book about index investing if you are going to invest.
