Well... maybe? SourceForge was always a really terrible experience for me, using it in say 2004/05. Loads of ads, interstitials and other general bad behaviour. It's not exactly surprising.
SourceForge used to be okay though already looked a bit dated, back then. Slashdot and SF were owned by the same company. Though adding adware to binary downloads is downright incorrect and alarming. SF doesn't even host the binary files themselves, they just provide an interface for various open file mirrors like HEAnet. HEAnet and co should block SF and we would need an open community website that links to the mirrors to replace SF.
