Given that the link is a duplication of the content of the original link, but hosted on a different domain, that one can view without logging into Twitter, and given the domain name of "xcancel.org", one might reasonably infer that the response from notamy is provided as a community service to allow users who do not wish to log into Twitter a chance to see the linked content originally hosted on Twitter.

Nitter was one such service. Threadreaderapp is a similar such site.
