Muratori, who is a well known C programmer and instructor, has made his dislike of Zig quite clear[1]. Others, like Tsoding (many videos) and Kihlander (doesn't like syntax among other things), have given clear reasons for their dislike of Zig or why it was not their preference[2][3]. Various recognized programmers are not going to go along with, "no downsides and all upsides". Which for any language still in beta, would be a huge stretch in believability, by itself.

It's not a Rust thing, as many C/C++ programmers are not advocates of it either and if venturing out to something else, can prefer other languages. Tsoding has even dunked on Rust as being unreadable[4].
