2003, apparently. The cause of the suit occurred in 1988, this writeup about it has quotes through 2002.

I could only find it going back to 2019 (https://web.archive.org/web/20191213165922/http://tomwaitsli...) but you're right, it does feel 2003-ey. We'll put that year above. Thanks!

I got the date from http://tomwaitslibrary.info/updates/. If you C-f for "frito", the only mention is 2003.
