You would be surprised.. I'm not sure many are aware.

The rebrand was to distinguish the token (STEEM) from the company (Steemit).

• The Steemit brand is protected under international copyright / trademark laws & requires written permission for any use/purpose

• the STEEM icon, the original we have all come to know is public domain - it may be used and modified without permission and used commercially.

Where you run into trouble is when money is exchanged in any form, it skates a fine line of commercial use. Best to avoid using the Steemit logo because it's hard to say what the outcome might be. I honestly have seen a ton of people using it, but advise against it because they'll likely make someone an example at some point. 😁
