You can work around this, though it's annoying to have to. Have it read
an environment variable or config file on startup, and use the spartan
output if it's set properly. This points out that "in the most normal
way" is undefined, but I doubt you'd get in any legal trouble over that.
Hmm. Reading 2c in a more evil way, the requirement is to "print or
display", but the exception applies if the original program "does not
normally print" the message. Ok, this is stretching.
The saving grace of 2c, which is frequently missing from other licenses
that attempt to force behaviors on modified versions, is that it does not
specify exactly what the message is, nor how or where the notice must be
printed or displayed. In fact, you could make your derived program spit
out a line to syslog which points to the copyright and disclaims warranty.
I'd still prefer it be gone, as it makes annoying some cases of extracting
functionality from interactive programs into easily-scripted ones.
However, it's much less onerous than those we routinely reject based on
