There are three basic reasons one might file a lawsuit.

1. To obtain regress for valid damages
2. To harass the defendant in order to force them to take a certain action

Number 3 seems to be right out, since Zoom apparently hasn't mentioned this
on his own web page. So we're left with #1 and #2.

You neglected to mention a fourth possibility:
4. The plaintiff is unreasonable (i.e. does not have a "basic reason [to] file a
lawsuit.").
