What if I told you those 3% of people will say this no matter what you do. These comments and the reality of your product are entirely disconnected. We had a small userbase and added voice uploads into the app; unsurprisingly, about 3% of them are clearly impaired in some way when they leave a message. [x-files theme].

In any case, a simple "Fast / Slow Setup?" question to start is all you need, and a "Do More Setup?" after they finish one item has, again, in my experience, been entirely sufficient.

Reasonable people understand, "oh.. this needs the cloud.. and I didn't do that part yet.. so I'll go ahead and click the 'social media provider' button." If you also decide this is a good time to ask about a news letter, well, you got what you bargained for.
