There is no problem. You're using an algoritm to generate smaller GIF files.
This algoritm is copyrighted (or at least: there's doubt) and cannot be used.
The GIF format is free to use, the compression algoritm is not.
The algoritm used by PNG can be used and distributed; this is why many programs
stopped using GIF and started using PNG.
Search the web if you need more info on this. Also see http://www.boutell.com/gd/
Much of what looks like rudeness in hacker circles is not intended to give
offence. Rather, it's the product of the direct, cut-through-the-bullshit
communications style that is natural to people who are more concerned about
solving problems than making others feel warm and fuzzy.
