for some people , encryption is a must because you never know what the govt. thinks is right or wrong and simply giving the govt. power to surveillance is quite powerful to govt. because then they can tweak that info into metaphorically speaking whatever they like.

there are entire communities based on this idea

For example r/privacy , https://discuss.privacyguides.net/ on which you rather have discussion on which protocol is more "encrypted" and "decentralized" in some sense to the extreme (like recent was simplex vs cwtch )
