One interesting aspect that I remember about this is the internal NNTP server with a newsgroup known as "Bad Attitude" where frustrations with the products, culture, structure, and other elements of Netscape were shared.
IIRC, "Bad Attitude" was eventually terminated, then a private group known as "Really Bad Attitude" was launched to a chosen few.
Microsoft managed to obtain all of these discussion histories in the discovery phase of its various lawsuits.
