I signed up because given the almost certain likelihood of random exposure at some future point, and the consequences of unwittingly infecting others, a controlled exposure was a net reduced risk. Caveat: I also commute by motorcycle, ride horses, sail, shoot, eat bacon, enjoy cigars, have been known to skydive, and swipe right on profiles that say, "no drama." So YMMV.
