Indeed, if you discount all the instances where it is true, it is not true.
From my understanding, Zed is GPL-3.0-or-later. Most projects that involve a CLA and have rugpull potential are licensed as some GPL or AGPLv3, as those are the licenses that protect everyone's rights the strongest, and thanks to the CLA trap, the definition of "everyone" can be limited to just the company who created the project.
