So the tidelift tests now fail for georgetown-cset/funder-finder because we now have tidelift in our README. :) How do you want to handle this? If we think many funded repos will just mention tidelift in their readme without a link we should keep the current behavior and change the test to another unfunded repo. Or if we think that most funded repos will include a link to tidelift, we could update the string to tidelift.com. Or we could switch over completely to this https://github.com/georgetown-cset/funder-finder/issues/35, although we might lose some repos that way

On the tests failing: Let's keep the current behavior and change the test case. Perhaps another CSET repo?
