To elaborate on my snark, this doesn't work because:

- Whitelisting my messaging app means I'd still get pinged for non-emergency messages

- Enforcing the block at the software level makes it too easy for me to disable it when the temptation arises. My current setup forces me to walk upstairs, flip the switch, then wait multiple minutes for the router to boot.

It would also take a lot more effort to set up, and time is money!
