Stripe Billing is not fully internationally available so a lot of software companies are opting for Paddle. A super API would allow users to easily switch between billing platforms and avoid lock-in.

The other reason is that Stripe Billing is stupidly good. So good in fact, that they could raise they rates from 0.5% to 1-1.5% and most people would pay up since migration would cause downtime and man-hours. I use Stripe Billing now, but could integrate with Lago once and easily switch between payment processors.
