In essence, because anonymization includes not being able to reidentify, and the anonymization process and techniques are evolving quite quickly, if you don't have this then what's the risk?
The risk to me is that perhaps it goes out of date, or organizations and companies are not keeping up with the pace of those generally accepted best practices.
What's the big risk, though, in terms of the public and privacy concerns? Mr. Chhabra, your comments really point to a risk that I haven't heard anyone talk about yet, and the main reason why our position is against removing this clause.
