The store was very popular during the early years of the iphone due to apple being more restrictive back in those days, its also worth noting that apple has implemented many of the jailbroken tweaks and applications making it less popular. The owner of the store creator Jay Freeman (aka Saurik) has shut down the Cydia Store citing a combination of costs and security issues. And while Freeman had already planned to close the store by the end of 2018, he brought it forward a week after learning of a security breach that let users purchase apps through their accounts if you were logged in and browsing untrusted app repositories.
This is not the end of jailbreaking it just the end of a centralised store portal users will still have access to Repositories to download, Freeman said, the necessary bandwidth represents the “majority of [his] costs” for Cydia and its just not worth it for him now to carry on. Jailbreaking will carry on but its obviously in decline. The option to run unsanctioned code was hot in the iPhone’s early days, when iOS had many more limitations and homebrew apps could enable major features like third-party keyboards which apple now allows. Apple also tends to patch security holes very quickly now. This is another reason why it’s simply not worth their effort to release one.
