18F was created by Obama because the way government was contracting private companies wasn't working.
Before 18F the government would pay $5 million to a private company for a basic website and they wouldn't even get it on time.
And it was ignored until Obama's most important legislation, health care, was threatened by a website, written by a private company for a lot of money, didn't work.
So Obama created 18F to fix it and then they expanded 18F mandate to do more fixing.
Clearly, the model of contracting private companies didn't work.
DOGE is literally the same thing. 18F was part of government agency that got renamed with executive order and had their mandate expanded to looking for wasteful government spending.
They just fired a small number of programmers aligned with previous democratic admin (18F) and hired small number of programmers aligned with current republican admin.
