Totally agree, if ancestry was republishing these resources or they weren't freely available then it would be copyright infringement/IP theft.
But indexing the content so those records can be searched and linked to on ancestry's platform? Totally fair game. If you don't want people indexing your content put it behind a log-in, you don't even have to charge for it.
