Apollo has recreated the easiest 5% of what reddit is.

Hosting at scale, content moderation (just the bare minimum to remain legal in various jurisdictions), plus all the internal bureaucracy that is involved in employing more than just yourself or a handful of people (complying with government regulations and paperwork for employee training, salaries, benefits) are all things that Apolloapp is not.

Getting a bunch of people to agree to not use reddit for two days (or longer) is a hell of a lot easier than getting that same number of people to agree to support Apolloapp as the New Reddit.
