I know, but GIF is still the graphic format of choice when it comes to
web graphics. This does not mean it is suitable for photos.

It is still an issue for web developers, believe me! Even though it has
been technically surpassed by PNG, how many websites are using PNG
instead of GIF? 1% or maybe rather 0.1%? There are not many...

No, not every program, but applications and libraries like GD, PHP and
ImageMagick should be able to handle GIF. Also, as I wrote before, GIF
support is not difficult to add. Simply dig out those removed code
lines there have been before they were removed because of those patent
issues.
