I think each plugin is going to be different. In general though, if the plugin needs to be activated by a user by changing a setting, I don’t know how you could modify the plugin to default to already on.

I think it will be different for each plugin though. I don’t use any of those plugins, so I’m not sure. If you post the URL for each plugin, maybe someone can look at the code and see if it’s possible to default them to active for everyone.
