Cultural identity and pride in one's lingual heritage play a part too. As a Dutchman, I like the German ß. Nothing conveys the notion of a foreign country better than another language and a differing orthography.
The ß even has a proper capital these days: ẞ. While no word ever begins with ẞ, you do need it when capitalising a whole word — e.g., on a sign.
