Wouldn't removing said splash screen violate section 2C of the GPL?
They might be able to modify it, but they can't remove it by my
A bigger concern would be an LGPL user re-releasing a version without
the splash as GPL. I'm not sure that the LGPL does what you want,

If it is all your code, then you can do that. But probably shouldn't.

No, because your costs are lower than 100usd.
Please remember that the GPL was written before most people were on
the internet. And back when most who were, were on very slow
connections. Therefore a distributer was likely to have to mail
software at significant cost. This term was protection for a
distributer to keep them from being out of pocket if many people
It is also worth noting that a primary beneficiary of this protection
was the Free Software Foundation. They distributed a lot of GPLed
software, and their financial resources were minimal.
