Nicole Sanchez, writing at GitHub:

Our first set of actions is in response to the recent executive order on immigration. We have chosen to support the US Muslim community through a gift of $25,000 to the Council on American-Islamic Relations (CAIR).

The United Arab Emirates labeled CAIR as a terrorist organization in 2014. The United States has not yet done so - hopefully it will during a Trump administration, along with the Muslim Brotherhood - but CAIR has ties to Hamas and nobody disagrees about whether Hamas is a terrorist organization or not. From National Review:

Hamas, designated a terrorist organization by the U.S. and many other governments, indirectly created CAIR and the two groups remain tight. Examples: In 1994, CAIR head Nihad Awad publicly declared his support for Hamas; the Holy Land Foundation (HLF), a Hamas front group, contributed $5,000 to CAIR; in turn, CAIR exploited the 9/11 attacks to raise money for HLF; and, this past August, demonstrators at a CAIR-sponsored rally in Florida proclaimed “We are Hamas!”

GitHub is giving thousands of dollars to a group that celebrates Hamas. In doing so, GitHub has crossed an unforgivable line. This isn’t celebrating inclusivity and diversity. This is celebrating terrorism and bigotry.

If I worked at GitHub, I would quit my job over this.
