This is a known issue -- the uBlock Origin extension completely blocks access to our site. However, you can set an exception within the extension to enable access. It should give you the option to temporarily or permanently "disable strict blocking for download.cnet.com."
The article R. Proffitt linked to was published in 2015. At that time, we used what was called the Download.com Installer (also sometimes called the CNET Installer), which did show offers for additional, optional applications while downloading one's chosen software.
We retired the Download.com Installer in February 2016, and it has not been used anywhere on our site since that time.
Some individual software publishers do still include optional, additional offers in their own install wizards, but this is not behavior specific to our site; rather, it is at the discretion of the individual software publishers. Our listing policies state that all such offers must be clearly disclosed and must provide a working method to decline or opt-out of them before proceeding with the installation of your chosen software. Any products found to be in violation of this policy are removed and their publishers notified.
