That was my first thought when I clicked on the website link in the Twitter thread -- expecting a disclosure/high-level info page in the fashion of the last decade of big-deal exploits with cute names -- and found only a tool the tweet author (not OP, but apparently working with him?) built that runs in-browser, requires no knowledge/setup, and appears to enable recovery of cropped-out image data at scale by even non-technical users. Jeez.

Edit: I find myself wryly weighing this against the ongoing unleashing of LLMs upon the world. Both have shades of clever people prioritizing being and demonstrating clever at the cost of... other stuff. On the bright side, it is distracting me from facepalming at the underlying Pixel bug.
