Yes, this message from the founder sounds very heartfelt and earnest. But if he truly could not anticipate the many ways that this service would be abused, and in fact the ways it is especially attractive to people with bad intentions, then he is profoundly naive.

It reminds me of Craigslist. Similarly well-intentioned, but eventually the company has gotta face the facts about how the service you're offering is conducive to bad conduct, even if unintentionally so. And if you can't build in sufficient safeguards, yes, it's practically inevitable that you'll face legal pressure.
