This is intentional. The installer does not install any spyware and clearly offers you a choice whether to install the offered software. If you need an unbundled installer, you can still download it from http://download.filezilla-project.org/
Site Admin, FileZilla Project Forum - 4th July 2013
FileZilla still uses SourceForge, but appears to no longer offer the modified downloader which attempted to install.
It appears that +SourceForge took over the control of the 'GIMP for Windows' account and is now distributing an ads-enabled installer of GIMP. They also locked out original owner of the account, Jernej Simončič, who has been building the Windows versions of GIMP for our project for years. So far they haven't replied to provide explanations. Therefore, we remind you again that GIMP only provides builds for WIndows via its official Downloads page.
In the past few months, we have received some complaints about the site where the GIMP installers for the Microsoft Windows platforms are hosted. SourceForge, once a useful and trustworthy place to develop and host FLOSS applications, has faced a problem with the ads they allow on their sites - the green "Download here" buttons that appear on many, many adds leading to all kinds of unwanted utilities have been spotted there as well. The tipping point was the introduction of their own SourceForge Installer software, which bundles third-party offers with Free Software packages. We do not want to support this kind of behavior, and have thus decided to abandon SourceForge. From now on, Jernej Simončič, who provides the installer packages, uploads them to our FTP directly, and from there they will be distributed automatically to our mirrors.
Some of you might remember that in November 2013, we abandoned SourceForge (SF) as the primary download site for the GIMP installers for Windows platforms and moved the files to our own download server, download.gimp.org The tons of links on the web pointing to the former site made keeping the installers there as well a necessity, though, and since SF claimed that our outrage over their "installer with benefits" was based on a misunderstanding, this seemed to be a low-risk approach. However we are receiving reports that people who get there by chance receive small installers that include additional software. And it's no clicks on those 'big green download arrow' ads this time, we've tried ourselves. SF has not responded to our inquiry yet, and we found that the maintainer of the GIMP for Windows installers is locked out of that SF project now.
GIMP never officially supported off-site builds, but this was used by their actual builder for Windows. Not any more though, as they claim to have been locked out of their account.
We also got outed of our VLC project on sourceforge... But it does not matter, we moved to our infrastructure a long time ago to our own, which is better and more powerful! They are the ones uploading the binaries there, not us! We left more than 2 years ago.

One indifidual claims VLC had the same thing happened to them a while back, but builds continued to be updated with adware. VLC links directly to it's own downloads on get.videolan.org
