Not filtering plugins

So I’m trying to filter active plugins on an install and basically it’s just not working, now I don’t know if I’m too dense or what but I just can’t tell how this exactly filters the plugins, I will appreciate your help.

I’ve setup a test on a dummy plugin and regardless on which part of the filter the plugin is it always shows the dummy output.

Here is the example of the test I’m doing, if my route has the test parameter it triggers, regardless of the plugin filter.

if ( $_GET['test'] ) {
	var_dump('test');
	exit();
}
