I can access Tutanota on Three UK, even with the filter enabled.<p>When this blew up last Friday[0], Three's response was, paraphrased, "you contacted the wrong department, here's how to contact the correct department. Their turnaround time is three business days."<p>Here we are three business days later, and it works for me.<p>This seems a bit overwrought?<p>(Content filters <i>are</i> an issue, but they're mandated by the UK government for large ISPs. <i>All</i> major mobile providers in the UK block by default. In an environment like that, false positives are going to happen; I'm not sure how this could have worked better in practice, so long as ISP-level blocking exists at all.)<p>[0]: <a href="https://news.ycombinator.com/item?id=33981873" rel="nofollow">https://news.ycombinator.com/item?id=33981873</a>
