Forcing users into steps they didn't choose could trigger reactance, leading to an increase in churn as people leave to regain their sense of freedom.
Steps that appear to force users into inviting friends may spark reactance, and could reduce the likelihood of them ever genuinely recommending the product.
Making onboarding steps feel optional, not mandatory, might reduce the discomfort and frustration that reactance creates when users feel controlled.
Letting users skip onboarding and click around at their own will could avoid reactance, and may increase how much they enjoy the product.
