When you modify GPL software:

1)  If you just use it "in house" (inside your company) you do not
have to distribute the the modifications. (But it is of course nice if
you make them available.)

2)  If you let someone else use the modified software you have to distribute it.

Maybe there is a "gray zone" for GPL software used on a web server?
