They’re also good for including in SMS text messages. Or print media. Or for typing into browsers on devices with sub-optimal keyboards (from my own experience, I can think of the Xbox and the Kindle)
Can confirm that SMSs are still a thing in enterprise. Several of my clients use SMS a lot. Given the character limits, they tend to prefer short links so they can give more info in the actual text. We've just migrated from goo.gl to bit.ly on two of them.
