Once you've launched with another service, you've already done the integration work, and Stripe's main value proposition seems to be its simple sign-up and integration process.

Once you've launched with another service, you may well be tied to them anyway, if they lock in your subscribers' card data. At best, you're running multiple services in parallel until all your early subscribers quit, or you're asking everyone to resubscribe and surely losing a significant number of people during that process.

And once you've launched with another service, you've permanently accepted their legal terms, which may or may not be a smart thing to do with some of the things these guys hide away in their contracts.

I certainly wouldn't wait for a company that says "soon" forever, but it's also not as simple as just signing up for any alternative you can find and hoping you'll move later. Of course you want to start bringing the money in, but as the saying goes, if you get into bed with the wrong partner for a night, the consequences can still last a lifetime.
