Anyone thinking that you can burry « whistleblower » with « whistle » (and it’s actually called cyberwhistle) has not checked how SEO works since 1998.
I mean, you could have just tried a google search before making accusations.

For me, 3 of the top 10 SERPS for "tesla whistleblower" are stories about this whistle product.
That's not exactly burying anything, more like promoting.
Burying would be if you were to search for "tesla whistleblowers" on Google and Google just giving you links to the whistle product, not allowing you to find the information you are looking for.
But that's not how Google, or any other major search engine, works, or has worked for a very long time.
So saying that's why Tesla/Elon are doing it, is quite simply false.
A reputation management company would be really happy with that result. They wouldn't expect one theme to fix it all.
