That exploit isn’t a full jailbreak. Basically someone found out to use the SmileBasic game to create a buffer overflow and inject their own program into ram. But still no real way to install homebrew as an app and open up the full Switch 2 for homebrew development . Every home brew program in that hack has to be run via the SmileBasic exploit. So unless you installed SmileBasic before it got removed that exploit is basically closed. And Nintendo is going to patch it anyway.
