Didn't Cydia shut down recently? I use Android, so I'm not really updated on Apple stuff, but I thought I heard Cydia shut down from lack of funding.Jailbreaking hasn't been the same in years. Most the tweaks you can install are nowhere near as fun as they used to be back on like IOS 7 or even 9.
I honestly have no idea. The last time I checked someone developed a tethered jailbreak for IOS 12 but it didn't even work on the newer devices so I couldn't even use it. Cydia was still working on it though.Didn't Cydia shut down recently? I use Android, so I'm not really updated on Apple stuff, but I thought I heard Cydia shut down from lack of funding.

It sounds like the creator just disabled the ability to purchase/monetize tweaks. You can still continue to download free tweaks so Cydia isn't necessarily dead. This might force developers to either make their tweaks free or discontinue their products from here on out. Purchasing tweaks was also never that big of a deal because you could just find someone with a link to a free copy of a tweak.
