Vitalik used to prefer permissive licenses to boost adoption,  
since they let anyone build on his work without worries.  
He also disliked copyright, favoring the "copyleft" philosophy.  
But now he’s shifting focus.

makes profit-driven motives harder to ignore.

Vitalik’s shift in focus is super exciting, showing how open-source is winning over big players and shaping the future of crypto
