I’ll accept that you’re saying you did this out of good will. So you too can accept that the results were not necessarily ideal, as many instances are not (or no longer) exactly Tor-friendly.
When talking to Tails users next time, you might want to consider nitter.oksocial.net (officially used by EFF too)
I meant the situation. Your assumption that Nitter instances are generally Tor-friendly (with only a few exceptions) used to be true, but anymore. The situation has changed and as such your understanding is slightly outdated.
