Hi,
Hats off to Yawning Angel for doing work to address this "CAPTCHA" challenge.
The idea of using archive.somewhere to fetch cached versions of walled garden internet zones seems sensible. More points to YA with the ALL CAPS warning about "big nasty adversary in you threat model dont go here" and "who do you trust ? archive.somewhere or Google/Cloudflare/other internet dominant organisation".
I use TBB because I dont believe that others have a right to know what I am reading, rather than because I face a specific threat. But, the act of deanonymizing to gain content access is a very slippery slope and I congratulate YA for putting effort into addressing this slightly obscure but very important challenge.
With respect, Hugo
