You can say that, but it's not.
Google CHROME is just 1 browser
they are not a monopoly, it's free for download, and it's freely available.
You don't need Google Chrome OS to get the browser, unlike with windows.
Windows IE for example only runs on perhaps Windows and OS (ie5 only),
Chrome has proper competition, equal market oppertunities: firefox, safari, ie, etc.
That said, Use the browser you want, but Safari 4 doesn't do WYSIWG on vbulletin 4 either, ..
chrome wysiwyg works just fine for me on various sites, just not vbulletin. same with safari.
it's up to vBulletin to support browsers, not for browsers to support forum software.
