The problem is this .. any search engine, whether it be Google, Yahoo, Bing, etc. - makes use of huge Metadata repositories, which then employ various AI, neural networking, semantic and confidence factor technologies. IF .. and that's a big 'IF', any of these Search Engines were to attempt to 'clean up' this data, it would be a MASSIVE effort and would cost them a huge ton of $$$. The breech occurred in Apple's iCloud product, why should Google or the other search Engines incur the cost of Apple's eff-up? That lawyer needs to consult with an attorney who specializes in intellectual property law.
If you think of this in layman's terms, this would be like going to every single library in the world and removing "certain" information/books .. feasible? .. not likely.
While I agree that what the hackers have done is TOTALLY wrong, I'm also a bit surprised that people would be so naive as to think that their phones can't be hacked (especially if using the "cloud"). Doesn't anyone remember the story about that cheesy tabloid paper in the UK (Rupert Murdoch) that hacked into various celeb phones? Bottom line, if a hacker wants at your data/pictures, they will find ways to do so .. especially on a phone which is a LOT more vulnerable than big iron.
Maybe it's me, since I work in Finance/Investments IT and so I have had to be on top of the latest in security measures, to ensure that your private data remains just that .. PRIVATE!
