TL;DR:

> In 2013, GIMP’s developers pulled the GIMP Windows downloads from
> SourceForge. SourceForge was full of misleading advertisements
> masquerading as “Download” buttons — something that’s a problem all over
> the web. 
[...]
> In 2015, SourceForge pushed back. Considering the old GIMP account on
> SourceForge “abandoned,” they took control over it, locking out the
> original maintainer. They then put GIMP downloads back up on SourceForge,
> wrapped in SourceForge’s own junkware-filled installer.
