No particular reason, Buddypress 2.4.3 is using ‘bp_actions’ hook to add its actions instead of ‘wp’ and according to WordPress you need to use the exact same hook with the exact same priority in order to remove a previously inserted action, i.e., now BuddyPress is adding its functions as:

add_action('bp_actions', 'bp_activity_action_sitewide_feed');

See wp-content/plugins/buddypress/bp-activity/bp-activity-actions.php (L530).

Therefore, they need to be removed using the exact same syntax:

remove_action('bp_actions', 'bp_activity_action_sitewide_feed');
