i don't quite agree because there are legitimate uses for UDP, but there are no legitimate uses for hand rolled crypto (except learning). also the issues with UDP mentioned in the article can easily be mitigated, which is not at all true for issues with hand rolled crypto. and there is one important use for UDP that is not well served with TCP or QUIC, which is tunneling. tunneling TCP over TCP does not work very well. also, the feature of mosh to keep a connection alive over network changes may not be easy to implement over TCP, i am not sure.
