Earlier quoted context omitted.
I'm more deeply concerned about the fact that Emacs is something which, roughly speaking, I can control. Emacs is a community project. Your project appears to be commercial in nature, regardless of whether or not it's open source. Your project will also be a dictatorship by dint of the fact that it belongs to you. Why should I trust you to provide the most fundamental tool in my work?
It will probably be under the GPL just like Emacs, so I'm not sure I understand the concern?
I'm fine paying for servers, for contractors, services, random productivity-ware like Pivotal Tracker etc. but I'm never going to be okay with subjecting my development environment, something I've honed for years and years, to fee extraction or proprietary control by a commercial entity.
