@harrysintonen @david_chisnall The email I received was pretty explicit that it's interactions with the slop that will be used to train and that if you previously disabled all activity feeding it then it also applies here, and mine remains disabled.
From April 24 onward, your interactions with GitHub Copilot—including inputs, outputs, code snippets, and associated context—may be used to train and enhance AI models unless you opt out.
If you previously opted out of the setting allowing GitHub to collect this data for product improvements, your preference has been retained— your choice is preserved, and your data will not be used for training unless you opt in.
