Andre Cronje, CTO of Sonic Labs (Fantom), posted on X that he had just seen a project worth $1 billion TVL and $1 billion FDV, which used the open source code he wrote (under GPL3) and attached a BUSL license.
He also said that he could accept not being recognized, and that they could remove his name from the code, not mention him or the original project anywhere on their website or documents, and do their best to reshape certain concepts to avoid any association. But taking something from open source and making it restrictive, the project party made a lot of money from it, and the changes in this field are much greater than I imagined.
