I think so.Is this good for the average domainer?
There are serious issues with their scraping of WHOIS within European jurisdictions. Look at how DomainTools handles .co.uk and .eu domains. There are also associated issues with their scraping of web content - DomainTools for example - we've found them not to honour robot.txt directives.
There are a number of serious issues on associating domain ownership from more than a single WHOIS lookup at a given point in time.
Historical WHOIS for example should be authoritative and subject to various legal requirements. For example one of the main reasons for WHOIS privacy is the safety of the website owner especially for contentious subject matters. Most users are not even aware of scraper services like DomainTools and how they are combining the data they scrape, therefore what happens if a Women's Refuge Center registers a domain in their own name and then converts to privacy before the site goes live?
Another problem is aggregating of all the domains someone owns. For example the previous owner was bragging that he could determine new products before the official announcements from companies from newly registered domains. This sought of thing just casts the whole domain industry in a bad light.
