If you'd like to convince scientists to come around to your line of thinking, explain the problems with current research papers. Tell them about the problems with publishing papers only, how others struggle to reproduce their research, and how it leaves much bad research that would be invalidated far sooner except that the information to recreate their trial was absent.
Then explain how sharing the code and data with Git (or similar) can solve this problem. You'll find that you are much more persuasive.
