Let’s be honest, one of the most-common uses of these archive sites has been paywall circumvention. An academics-only archive might make sense, or one that is mutually-owned and charges a fee for lookup. But a public archive for content that costs money to make obviously doesn’t work.
if that’s the real motive, why don’t they allow access to scrape content after some period? when that news is not as relevant. For example after 6 months.
