That quote from the article directly-contradicts what multiple tour-guides at the Winchester Mystery House in California have told me over many decades. Specifically: Sarah Winchester built the house because she was told that the ghosts of all those killed by Winchester guns would haunt her unless her house was sufficiently labyrinthine, and endlessly expanding; to confuse them.
Visit the house (the tour is rad) and see for yourself the architecture. There is no reasonable explanation for internal doors leading to sheer-drops, throughout the house, and other bizarre 'traps', apart from Sarah legitimately believing she had to confuse the ghosts.
This is more akin to a programmer consciously obfuscating and expanding a codebase to make it impossible for their angry-users to ever finish auditing it, or to determine its author.
