One problem with self-hosting is that getting security right and tight is really hard. You have to be aware of all the components used in your stack, and monitor them all for known security problems. And then know how to react to them. And then you probably want backups, and monitoring, and what not. Ideologically I'm fully a favor of self-hosting many bits, but having some experience with it, I'm also acutely aware of the downsides.
