Recently SF hijacked its hosted projects to distribute their wrapped crapware:
SourceForge grabs GIMP for Windows' account, wraps installer in bundle-pushing adware
Black “mirror”: SourceForge has now taken over Nmap audit tool project
What happened to Sourceforge? The full story between VLC and Sourceforge
Obviously, the paid component per installation system is one of their important income generating scams. I would be fine with that, if they were the actual owners of the legitimate software. The real problem is, they are polluting these open source software installations for the purpose of filling their pockets by this scam, and worst of all, without even notifying the authors/creators of this software, while the creators are struggling against such parasitic software in order to keep their installers cleaner and safer.
Such a shameless policy should be condemned, and the Notepad++ project will move entirely out of SourceForge.
I humbly request that Notepad++ users not encourage such scams, and educate others not to download any software from SourceForge. I request as well that the project owners on SourceForge move out of SourceForge, in order to preserve the purpose of the Open Source Community and encourage the works of true authors/creators.
