Comment (by matsubobo):

 I think I understood how plugin is activated on multi site.

 I also tried following code to analyze the plugin is activated.
 {{{
 function myfunction($content) {
         print 'this block is passed.';
         $content = 'test'.$content;
         return $content;
 }
 add_filter('the_content', 'myfunction');
 }}}

 "'this block is passed."  was displayed but "test" was not displayed on
 child-sites.
 Both "this block is passed" and "test" where displayed on the main site.
