People may be wary of allowing certain types of content to be hosted or distributed through their nodes. It is important to realize that there needs to be a shift in belief on all sides for us to make widespread use of decentralized tools a reality. There are institutions and organizations that have only ever known and felt comfortable with top-down, centralized methods of enforcement or management. What we're offering is a completely decentralized way for people to be empowered and follow their own ethics and beliefs. If one disenpowers people entirely, they may become afraid and try to lash out with centralized hammers (e.g. outright bans, etc.).
It is important to realize that not everyone in the public, etc. shares our beliefs and furthermore not every country has the same laws.
