This is addressed in the panel. The argument is that there is some "privacy mixing" because owner of the authoritative server only sees a highly-trafficked resolver as the source, and not your home network resolver.

In the first case a client that request a webpage contact company X authoritative server with private information [IP ADDRESS], creating a record on the DNS server, and then visit company X web server creating a second record at the same company with the same [IP ADDRESS].
In the second case a client request a webpage of company X by contacting google, creating a record on google DNS server with [IP ADDRESS], and then visits company X and create a record there with [IP ADDRESS].
In one case one company has the data, and in the second case two companies has the data. It does not make any sense.
