Ex-Twilio here too.. and worked for an SMS aggregator before that. While working with one carrier is easy, working with 5, 10, or 100 is a horrible pain in the ass. In addition, you need a compelling reason to convince higher ups in your org to sink $texas-sized dollars into this.. long before you can send that first message. Uber is a special case as they needed coverage in countries that Twilio didn't support. Further, they had a ridiculous pile of money. Since they had to stand up the architecture anyway, adding the "easy" countries made sense.
