Why do the analysts believe that the leaked PoisonFrog and Glimpse tools are unlikely to be widely misused?

The techniques they employ, such as DNS protocol tunneling for data transmission, are considered outdated, reducing the risk of large-scale adoption, as discussed in the Analysis of APT34 Leaked Tools - PoisonFrog and Glimpse article.
