I was the original programmer for that project...while I didn&#x27;t enjoy spending part of my late 20s learning about PDF to text conversions...I wouldn&#x27;t necessarily attribute their use of PDF to devious motives. It&#x27;s easy to forget sometimes that much of the world still operates on paper...and electronic documents that translate directly to paper have some value. These financial records were disclosed as part of legal settlements, and they were also used by hospital compliance officers...While obviously just sending out CSVs or Excel sheets would be great, it adds a possible breakage point between the company and its audience...i.e. hospital officers complaining that the spreadsheet looks funky on their version of Excel or whatever the hell they&#x27;re using. The thing that makes PDFs so frustrating to parse is what makes them so &quot;secure&quot; and stable to end-users. That&#x27;s why I advise my students to not just send URLs and web-clips to potential employers, but to have PDF versions of their resumes and work because inevitably, the &quot;boss&quot; wants a printout on his desk...and you don&#x27;t want his office&#x27;s shitty printer (and&#x2F;or whatever IE browser rendered the HTML) to leave a bad first impression.<p>And let&#x27;s face it, if you are an end-user who is not a programmer, a PDF is very convenient. You can even do Ctrl-F to look for things...and if you aren&#x27;t a programmer, that&#x27;s all the search-power you need to do your compliance work. After the investigation was published, I fielded a lot of questions from auditors who were convinced I had built some amazing proprietary search algorithm...such people just don&#x27;t know the gap between doing Ctrl-F versus &quot;SELECT * FROM doctors where LAST_NAME like ...&quot; :)<p>There were a couple of companies who arguably went out of their way to obfuscate their records. They had built websites that consisted of Flash widgets designed to look and act like a (crappy) HTML table...except with Flash, you can prevent the user from select&#x2F;copy&#x2F;etc. Unfortunately, the developers of those widgets never told the companies that their Flash containers operated by making XHR requests to external XML&#x2F;JSON files...so these companies ended up being the <i>easiest</i> to gather the data from.
