Quote - Is there no way to have people downloading zips to agree to the TOS prior to downloading? Sort of a restricted access to the download unless you agree to it? Just a "Check this box" click ok and you download the zip file?

The basic flaw in EULAs for digital content and software is that you don't see the EULA until after you've bought the product. In the case of software in a box, you don't see the EULA until after you've opened the box, at which time the vendor won't take it back (due to the slimy practice of copying the material off the disk and then asking for a refund). 

So you buy some digital content from DAZ or Rendo or anyone. Upon installing you read the EULA and find it too draconian for your taste. Too bad, you already bought it. Your options are to install and agree to the EULA or not to install. Most people don't even read EULA any more because they feel it doesn't matter what it says or how they feel about it. If they want to use the product they paid for, they have to click AGREE. So they click without reading.
