I'm not so sure they are popular for the right reasons, though. When targeting anything server-like developers quickly grab something like docker desktop as a kind of poor-man's Linux. Apple has no OS or cloud platform presence. Also, so far it has shown little interest in supporting Linux community hacking away on apple silicon (Asahi).
Apple Silicon is very expensive to manufacture. Only Apple and Nvidia and few others have profit margins high enough to outbid others to get access into latest TSMC process. They pay premium.
Server chips should be power and cost efficient. Intel has still 70% market share in server CPU's because they have their own fab. AMD has close to 30%.
