Is not up to SUSE's marketing department, most of which is from the US, either. The company has a German origin, had German founders (they're all out of the company at this point though), and the company name used to be a German acronym. The correct pronunciation is the German one.
(See the update @barbara added. Lisa Sherwell actually took the effort to learn the correct pronunciation. Part of the reason why is that she was actually involved in planning the new German office of SUSE.)

phishingurl
indicates that it's part of some URL checking functionality of a browser. Not sure which browser puts that straight into.local/share
though. Might be a KDE thing.Edit 2: Qkall's answer says it's KMail.
