Does Zed have "I work for corp where ie. only github copilot is allowed, I don't want free auto completions or anything that sends code to 3rd party" flag?
Last time I checked (about half an year ago) it was hardcoded and unconditional, so disabling it required a patch.
At the moment it seems it's great for personal development and development in environments where concerns around IP are less of an issue.
It's not so clear how to use it in corporation context where you'd be in breach of employment contract accidentally because defaults mean sending confidential IP to 3rd parties.
