Major efforts at creating "everything" libraries are usually looked upon as a positive effort that benefits all of humanity, and we generally mourn the loss of any such effort, regardless of whether the effort is against the laws of the state at the time the effort was undertaken, or even if the collection was created in a morally reprehensible way.
See: Library of Alexandria, Library of Congress, GenBank, the Svalbard seed vault, Google Books, Internet Archive and all its efforts, ...the Louvre, and most major museums.
In general, we collectively recognize - without having to be told - that preservation of knowledge is a noble and worthy effort that transcends the fleeting whims of a population at a point in time.
All that to say, people probably don't need to be tricked into liking such efforts. They're popular because of what they are.
