Prices were set so that if a user used every text and call minute allocated, the company broke exactly even on Twilio costs after Apple's cut; any unused allowance (breakage) was profit.

What happened

It was generating debate. You can't recreate that today. Like you said, it's not South by Southwest in 2012, but analogs of that exist today on TikTok and Instagram and anyone can go viral for a feature.
