You're an idiot if you're complaining about this. The EAS (and its predecessor, the EBS) has been around for almost 50 years and is a necessary, though at times potentially ineffective, capability to have. From the mid-90s into the late 2000's there was concern that the "traditional" methods of activation would be come less and less effective.
Every single broadcast TV and radio station has a manual right in the control room and there's an out-of-band method for heirarchical distribution of messages from local relays to cut in at a moment's notice.
The problems were that people nowadays were spending more and more time away from live, regulated broadcasts, and with cell phones instead of land lines (for reverse 911 calls in the event of an evacuation).
Extending these regulations to "channels where people are actually spending their time" is an important part of keeping the system relevant. Cable systems have been doing text overlays (scrolling text for EAS tests or NWS alerts) for a while, but that now cuts through into your cable-provided DVR if you have one. Netflix and other streaming providers have ways of injecting data into the feed. Hell, at a game company I used to work for there was talk of using zip code subscriber data to forward NWS alerts to users *within the game* to ensure that someone didn't miss a tornado warning if they were spending the evening with their favorite MMORPG and the radio off.
Extending this to cell phone towers and multicast paging simply makes sense. It's not nefarious, it's just good public policy.
(And this is coming from someone definitely of the libertarian-conservative mindset, and no fan of the current President.)
