You can feel free to use the Steem logo instead. The purpose of this policy is to enable us to protect the brand and the community from malicious actors like people who are seeking to defraud others through phishing schemes (as just one example). We have no plans to file suit against innocent users, however, if we find that use of our brand could be confusing to people we may ask you to remove it. But we must always retain the right to file suit because if we do not we lose that right. The important point is that this policy is not a money-making scheme and we do not intend to use it as such. It is an important way to protect the site and the community members.
Community Liaison, Steemit
