Even GiveWell partnered with the long-termist/hypothetical risk type of EA by funding something called Open Philanthropy. And there are EA organizations which talk about "animal welfare" and mean "what if we replaced the biosphere with something where nothing with a spinal cord ever gets eaten?" So you can't trust "if it calls itself EA, it must be highly efficient at turning donations into measurable good." EA orgs have literally hired personal assistants and bought stately homes for the use of the people running the orgs!
