   [...] I click on the URL and application is in the browser ...

I think that sentence sums up the overall problem.

In Emacs, since you gave that as an example, when you install a
package, the list is curated.  Same with your GNU/Linux system.  When
you copy a snippet of Emacs lisp code, you will see the license text
and can decide what to do before running the program.

Had non-free software been irrelevant, web browsers executing random
code (if we can wish for a world where non-free software is
irrelevant, we can wish for software without security issues :), then
the Javascript trap wuldn't have been a trap.
