Explanation

Ambox notice.png This explanation may be incomplete or incorrect: Created by AN UNENCRYPTED SMS. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.

Messaging systems suffers from the Network effect, as in order to communicate, both parties need to have adopted the same system. Though relatively ancient by modern standards, SMS is supported by most every mobile device (unless you're still on a DynaTAC) that has a phone number attached, which means if you want to send a message to someone, but aren't sure if you have a messaging app in common, you can be sure at least they have SMS.

The comic mentions many other communication systems, which offer various advantages in either security and or a bunch of general improvements filed under the label "vaguely modern", such as longer character limits and the ability to share media such as images in-service.

Vaguely Modern

Slack

Slack is a workplace messaging service which offers the ability for administrators to create channels in order to organize the discussion. It is asynchronous, which means that conversations can occur out of time, hours apart from each other. It also keeps track of every message, and everything in a public channel stays there forever for everyone to see. It is not encrypted, and has been moving towards being less privacy focused for end users over the years as corporate demand for employee surveillance has prompted the company to offer ever more invasive services to administrators. Overall, it is a popular service with some large companies and non-profit organisations, but does not yet have universal adoption.

Facebook Messenger

Hangouts

Google Hangouts is a messaging service which can be accessed through the online Gmail Client, as a separate web page, and a standalone app for the phone. While theoretically that means everybody has access to it, modern usage patterns means that most people do not use the attached web client and don't bother downloading the app. It allows users to upload significantly degraded images, links, and other media along with text with a copy-paste.

Discord

Various DMs

Vaguely Modern & E2E Encrypted

Signal

iMessage

WhatsApp

E2E Encrypted

PGP Email

Various Obscure Projects

Skype I Think

Jabber + TLS

Supported By Everyone

SMS

SMS is a text messaging service formally defined in the GSM standard in 1985 and first used in 1992. It limits users to being able to send up to 160 characters, and only text.
