They think they know better than what the user wants. If someone who is not a power user Googles "how to turn off updates" they do not want that user to be able to find an option on how to do it, because the user won't understand the dangers. They won't read any warnings. They will follow the steps, turn it off and be part of a botnet soon. If there is ANY possible way to turn it off, someone will make a video and the people who should not find it will find it.

What if you are ACTUALLY someone who knows what they are doing and need to run a perf test over a multiple day period and need it running and uninterrupted? You can't. You are not a part of their target customer base, and at this point their actions have made it clear that they want such users to leave.
