DoT works on port 853, so it’s easy for ISPs to spot/block it. They can’t do the same for HTTPS.

- zzzcpan 7y agoNo, they still can spot and block it. The only way it can be hard to block for an ISP is if DoH used domain fronting style collateral freedom, but that didn't turn out to work in practice as governments found even the largest corporations to be acceptable collateral and just blocked IP ranges of those corporations to pressure them to disallow such thing and of course they all pretty quickly disabled domain fronting. At this point there is no way big tech corporations can get involved in censorship circumvention, but they can and are in censorship both to satisfy all the governments and for their own benefit.
