Intra VS GoodbyeDPI

Other than that, Rethink is a proper network monitor and a (tcp/udp) firewall; while DDG is a browser bundling in DNS-based protection, from what I can tell. DDG is based on NetGuard, but they don't license that tech as FOSS but only under source-available license. Rethink is fully FOSS, and it was initially a fork on Intra, but it has diverged very much from Intra that it is no where near similar to its predecessor, anymore.

Intra: Encrypted DNS client

Haven’t used Intra before but it looks like it uses Google’s Firebase analytics (https://github.com/Jigsaw-Code/Intra/blob/master/Android/app/src/main/java/app/intra/sys/firebase/AnalyticsWrapper.java) (no surprise though since Intra is by Google (Jigsaw team)).

Right now, it is accessible only through VPN. Even programs like DPI blocker are not helping

As in you cant access those sites (you got redirected to the ISP site)? Try changing your dns (make sure to clear your dns cache too) and try using goodbyedpi. Recently my country start enforcing isp to block piracy sites along with other sites (porn, reddit, etc) but since their method is just to use dpi, i could just use goodbyedpi to bypass it.

Russian internet censorship is very simple. They don't seem to be using DPI to target VPN protocols at all, instead trying to block IPs/subnets of known commercial VPN providers. Blocking IPs, subnets, and domains is the primary operating mode of Roskomnadzor.

There allegedly is DPI, but it only comes into play as an extra measure against things like domain fronting, proxies, and plaintext HTTP. It'd look at the SNI and inject a RST packet to drop the connection. As it does not even try to implement TCP, analyzing each IP packet in isolation, there are various interesting utilities[1] that mess with it by, for example, splitting the TLS ClientHello into two TCP packets in the middle of the domain name.
