Alegado opposes the construction of the Thirty Meter Telescope on Mauna Kea, since it represents a continuing infringement on native lands, and has spoken out about the issue to the media. She has written to counter the idea that the native Hawaiian culture is acting 'anti-science', describing how the local philosophies that hold the mountain sacred are based on concepts of environmental protection, and stating that it is dangerous for science to continue unbounded by ethics, anti-colonialism and respect. Alegado and other Native Hawaiian academics wrote a paper in ArXiv which detailed the local case against the telescope and how to improve relations between indigenous people and astronomy.
