It drives me crazy when sites block access via #Tor to read-only resources (like articles)---it doesn't make much sense to me. It's probably a quick decision by a team of people that don't really care or think about it, but it has strong effects that in the best case discourage use of an important privacy/anonymity tool, and in the worst case outright prevent certain users from accessing those resources (if Tor is their only option).

A common workaround I use is to prepend "https://web.archive.org/" to the URL to load it in the #WaybackMachine from the Internet Archive. Sometimes websites block even that.

The Internet Archive does great, important work, btw. Here's a recent article that emphasizes some of the major problems they're solving:
