Would it be possible for libraries to provide email addresses through their own mail servers? Certainly Google has an enormous number of issues, but I can't see them weighing in favor of the elderly and less fortunate over the high profile users whose accounts are constantly targeted. I also have doubts that any bypass solution would succeed due to necessarily requiring users to both know their existence and properly set them up; not everyone has technical competence nor the experience to know for which resources to seek.
