What specific concern do you have in mind? Are you aware that the corporate structure of Vanguard is that it is the funds who own the company, not the other way around?

why would the active funds fail?
if you have 1.1 million in the bank you can afford to take $500 to poker tables
My main issue though is that Vanguard's brand is low-risk passive, but they are now selling high-risk active funds under that brand.
But Vanguard under Bogle always played both sides of the fence at least to some extent. They have always had that actively managed Windsor fund, right? And Wellington?
I think your article headline shows you have a fair bit more to learn about Bogle. Or at least you haven't made your case on that front. Bogle was at least as much about low cost and aligning interests of the investment client as he was about passive indexing, though he is known more for the latter.
Here's a writeup with a couple pointers to more on the topic from Bogle: https://www.bogleheads.org/forum/viewtopic.php?t=388377
Quibbling over one basis point in fees just doesn't feel valuable. Tracking error will be larger than this.
