Because Rust is cool and JavaScript sucks
Yeah as much as I love ublock origin and use it heavily. I support more rust on more things. 60+% of browser CVE are memory issues. Rust was explicitly made to stop those.
Do you think that Javascript has manual memory management?
No, but it's nowhere near as strict in its management. Plenty of memory issues can still usually from unintentionally maintaining a reference to an object. forgotten global variables, uncleared timers (setInterval), or closures that stay in scope longer than necessary.
And ofc you now have the performance overhead of GC constantly running
