First, URL shortening is not what this tool is for.
It will function as a URL shortener if you put in a URL and tell it to, but again - that's not what it was built for.
Second, I tend to agree with the notion that URL shorteners are "bad for the web". So, since we happen to have a (secondary) URL shortening function, I did two things:
1. Made a commitment with actual resources to keep 0x.co running forever.[1]
2. Had a short discussion with my friend Jason Scott[2][3] about giving Internet Archive and Archive Team an easy port for download/archiving. In our conversation he reiterated his (well known) position that URL shorteners are bad in general, but less terrible if there is a published (and maintained) spec for data exfiltration.
But again ... URL shortening is NOT what this tool is for.
[1] simple, lightweight pages combined with massive, leftover rsync.net bandwidth/hosting resources make this trivial.
