Comment (by alecmuffett):
Note for anyone saying that (eg) "to preserve privacy, Facebook should
simply offer Alt-Svc headers on all its requests", some basic math:
{{{
strlen("Alt-Svc:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.onion\r\n") = 73
Facebook does more than 1 trillion requests per day.
73 trillion bytes in terabits => 584 terabits
}}}
Are they willing to sacrifice the environmental and energy and monetary
costs of causing 584 terabits of global daily traffic, on Facebook alone,
for the potential sake of one or two million users (ie: about 0.1% of the
Facebook userbase)
Frankly, I can't see that being justifiable in any way, when instead
TorBrowser could just identify itself and let Facebook [and everyone else
- BBC? NYT? Other social networks?] selectively offer {{{Alt-Svc}}}
instead.
