Chances are the consequences of violating the law are so non-threatening, it's just "the cost of doing business", and by the time government decides to take action, the data is already in their hands anyway.

Not correct. The task manager can do that.

Memtest can't show you what uses your memory because it doesn't run in userspace on the desktop. It only runs stress tests on RAM to make sure the modules can read and write data without errors.

Please elaborate on how a software package that tests memory before any kind of OS is even loaded is supposed to help bring back user privacy.
