Ive been using it (the original 15 tool version) for months now. It’s amazing. Any app's inner workings are suddenly transparent. I can track down bugs. Get a deeper understanding of any tool, and even write plug-ins or preload shims that mod any app. It’s like I finally actually _own_ the software I bought years ago.
For objective C heavy code, I also use Hopper Disassembler (which now has a built in MCP server).

Talking about RE'ing applications and equating that to OSS is not a good look when you work at GitHub...
