As stated by another poster, Netscape vs MSFT was about coercing OEMs not to include competing browsers to be pre-installed on new systems. Apple could create and give away a cross platform password manager without much fear of ramifications, unless they exclude all other password managers.
(e.g. Netscape vs Microsoft Internet Explorer)
EDIT: why the downvotes without a reply? If you don't agree, why not just respond why so that a health dialogue can occur.
