But owning a smartphone with a touch screen (instead of tin cans connected by a string) and having the luxury of choosing between Uber vs LibreTaxi (instead of waving your arms on the street to hail a taxi) is also a 1st world problem. If we're discussing percentage of world market, 51%+ do not have combined attributes of (1) smartphone ownership[1] + (2) Uber availability + (3) preference for paying cash.
For customers, one of the key attractions to Uber is that drivers can't play the game of "oh sorry my credit card reader is broken, you'll have to pay cash". In other words, many customers deliberately choose Uber as way of not having to pay cash. (This point is more relevant in Uber-USA and not Uber-India that allows cash payment.)
The developer name I see on the LibreTaxi page is "Roman Pushkin, San Francisco, California" and since he's based in a 1st-world location, it seems like the Uber-vs-LibreTaxi has relevance to cashless people like me. If he intends for the service to be used mostly by 3rd-world countries where cash is king, I misunderstood the point of the Uber vs LibreTaxi comparison.
EDIT ADD 40-minutes later: I found author's comment on the intended market of customers: "Just started http://libretaxi.org - uber alternative for communities and remote regions." : https://news.ycombinator.com/item?id=13328052
also see: https://news.ycombinator.com/item?id=13530355: "Uber, a company evaluated at $60B, will unlikely go to remote Siberian region where I was born."
Conclusion: LibreTaxi isn't really a competitor to Uber -- it's more of an alternative to remote villages having no ride sharing at all and therefore cash payments makes perfect sense for that market.

Since that article prices for smartphones have tumbled again. I bought a smartphone, quadcore, 4GB, built in TV, Built in radio for P1,700 (about $34) Its a cheap phone, but it works fine. http://ph.priceprice.com/MyPhone-my81-DTV-17896/
In Vietnam it's the norm to have a smartphone but it's seriously difficult to get hold of a normal debit/credit card.
I've been in Qatar for business. Coming from the US, it is shocking. Some systems have leapfrogged -- e.g., ease of banking, 2FA, mobile phone plans, messaging, ride-hailing apps, etc.
Other systems lag -- the most egregious example being the lack of a national address system. Correct -- i have no home address. Half the country does not -- people send GPS coordinates and WhatsApp location pindrops for ride-hailing and food delivery.
