The Register reports that the original system TACO has become proprietary and has added new "features" best described as bloatware. I guess this should serve as a warning for users to always prefer software under a copyleft license where possible and best if any company involved has handed it over to a foundation such as the FSF or KDE e.V or Apache foundation which will guarantee that future releases will maintain their F/OSS character. If Google had chosen a license with better protection, such as the GPL, when they released their opt out tool this problem would have been much less likely. This also shows why forks are so important when software development begins to get messy.
