XMPP, Browsers (early days and why Internet Explorer is so widely known), Microsoft broke Java compatibility with non windows systems by replacing the native interface with their J/Direct breaking programs for other opwrating systems, MAPI has been accused of doing this to IMAP and POP3 (tho not to the same degree).

Here is a quick wikipedia page if you want to update yourself. There are plenty of battles to fight today, too. Its understandable to not have the will or want to get into it.
