You're right that "studies" is designed for distributing/testing experimental features, among other development and debugging uses. I'd dispute any characterization of LookingGlass as a FireFox feature though, and feel very strongly that using Studies to distribute marketing software (inert or not) was an entirely inappropriate use of the tool. Mozilla being willing to use Studies (or having a process that allows for it to be used) in this way means that, although I was fine with the extra telemetry, debugging, a/b testing, etc., I cannot trust Studies to be used strictly for development related things.
