Google appears to have upgraded the JS part of the page performing an explicit post request to acknowledge ToS is accepted by user. As such the links index page content is not revealed until user triggers that request.
The request is against the "profile/acknowledgeNotification" URI and seems to bind with a XSRF token generated by the developers subdomain and NID generated from master google TLD. The second part is kind of weird since if user has never visited any google.com TLD before browser cache doesn't have a valid NID to use and thus cannot access the developers page (you can reproduce if clear all cookies & cache and jump directly to nexus devs website).
Investigate if the above mechanism can be performed from command line, otherwise the auto download feature needs to be stripped out and users have to manually perform image downloads prior to generating the vendor blobs.
