Adobe is not exactly a champion of user privacy. In addition to the high profile hacking case of a few months ago, they also got caught red handed data hoarding on ebook users. And that’s before you consider all the issues with the Adobe PDF Reader software and Flash. So if you want to limit your exposure to Adobe’s data hoarding a little bit more, there is one option in your Adobe.com account profile that you can control, it tells Adobe not to collect “Desktop App Usage Information”. It is turned ON (ON = collect data) by default. I have no way of knowing how much of the spying/data-hoarding this will curtail, so don’t assume this is a catch-all safety net.
