there is a link in in old HN post (https://news.ycombinator.com/item?id=2910554) that no longer works: http://cnet-upload.custhelp.com/app/answers/detail/a_id/2064
anyone know if there is good contact form or email address for any of these download sites to ask that they not offer my app?
If I am not successful getting them to comply, would a DMCA be appropriate and would I be asking for legal troubles if I submit a DCMA?
If your software is MIT licensed or similar, you can still ask, but you're probably SOL if they don't agree to remove it. With those kinds of licenses, they're under no obligation to remove it just because you ask them.
Simply contacting them at any of the email addresses listed here: https://www.cnet.com/about/contact-us/ or calling them should get you routed to the right person eventually. You could also try generic emails like legal@cnet.com, abuse@cnet.com, dmca@cnet.com, etc. In the worst case, here's a list of CNet employees: https://www.cnet.com/about/meet-us/ - figure out their email format (e.g. firstname.lastname@cnet.com) and shoot them some emails.
However, you should be prepared for them to simply do nothing unless/until there's an attorney involved.
Do you stand to lose income or receive some other kind of material injury if they don't take it down?
Edit: The help center at the bottom of the Download site took me here: https://cbsi.secure.force.com/CBSi/articles/en_US/Knowledge/... - this might be what you want?
edit: ah sucks, seems on Windows this only gives you the network zone the file came from, not the URL. I think on OS X it is definitely the URL though https://superuser.com/questions/1513910/windows-extended-att...
Obviously your app cannot do this now.
Hope this could be useful to others in the future.
Just the threat of legal action may be enough to get them to remove it.
But they do a lot of misrepresentation (apart from other slimy things) and you are well within your rights to object.
As another posted commented: this is what filling a dmca claim is for, and you can do it without paying a lawyer or anyone else. The only problem is whom to send it to. You’ll find that CNET’s download is actually download.com. You’ll have to start there.
