Currently people can access FTP list and download resources hosted on FTP servers in Chrome through FTP URLs, but this may not work anymore in the near future. In a post published by Chrome engineers, there is a plan to deprecate FTP support in Chrome version 82.
The major motivation for this deprecation is that Chrome doesn't have an encrypted FTP connection support(FTPs), this raises security risk of downloading resources over FTP. Since users can access FTP URLs and download resources, there is no encryption of the data which indicates any sensitive information would be exposed to middle man attack. There are other vulnerabilities as well.
[...] The deprecation will start from Chrome version 82 planned to be released in 2020 Q2.

When SourceForge was owned by Dice Holdings, it distributed FileZilla and a bunch of other FTP clients with "DevShare" adware attached to them. This practice lasted from mid-2013 to early 2016 and ended when BIZX took over SourceForge and Slashdot.
