You mean wording like this?
""Mozilla doesn’t sell data about you (in the way that most people think about “selling data“), and we don’t buy data about you. Since we strive for transparency, and the LEGAL definition of “sale of data“ is extremely broad in some places, we’ve had to step back from making the definitive statements you know and love."
Which is contained in both the link you provided, and on their official Privacy FAQ: https://www.mozilla.org/en-US/privacy/faq/
I'm really confused how you can possibly claim that they removed the wording when it's right there for you.
