Talk about delusions of grandeur. He knocked a few public facing HTTP hosts offline, amazing! I can “a bring down North Korea’s internet” aka a few public hosts for a week too if I rent Lizard Squads stresser for $400 a week. What’s supposed to be impressive about that?
No, he knocked out the two routers serving the entire country. NK sites were inaccessible to the outside world, and outside sites were inaccessible to NK.
But very very few North Koreans even have access to the internet. Regular people just have access to a local intranet with censored information.
That exercise that Russia did a few years ago to see if they could function cut off from the internet? For north Korea that's the regular self-imposed status quo. I don't think it will have had much impact on daily life there.
Why install additional packages which bog down my system when I can use a webapp? What about for users of machines where they lack privileges to install packages?
27MB is bogging down your system? And yt-dlp does not need admin privileges to be installed. All it needs is Python3 which is, if not ubiquitous, excessively common.
Fun fact, I have vanity numbers ending with NNN-0001 and 0000 on my cell phones and I have revieved ZERO telemarker calls to date on either number. Whatever mass calling software telemarkers use, they won’t call numbers that look obviously fake.
Organized crime networks have insiders/hacked machines at the phone carriers where they can perform IMEI lookups in the carrier database to get the subscribers phone number.
As an Android user, I'd counter "Signal". Which I think would bring things back to what another comment mentioned about preferences in messaging platforms.
