For years, people with jailbroken iPhones have turned to the Cydia Store to download apps that Apple wouldn't allow through its own portal. You might want to scramble for an alternative if you're one of those users, however. Service creator Jay Freeman (aka Saurik) has shut down purchases in the Cydia Store citing a combination of costs and security issues. It "loses [him] money" and, when there were multiple staffers, cost him a significant chunk of his "sanity." And while Freeman had already planned to close store purchases by the end of 2018, he bumped it up a week after learning of a security hole that let let someone buy apps through your account if you were logged in and browsing untrusted app repositories.
