Trying to understand why Laravel's many static methods is not considered bad practice

I'm pretty confused.

I've asked a few developers on Reddit to review my codes. It looks like this.

Template::load('register', array('error_message' => Language::translate('username_in_use'));

So it loads register.php, replaces {error_message} with translation. (Sorry, this username is in use. Please pick another.)

They said using too many static calls is a bad practise. Yet they suggest Laravel framework, which completely gets rid of $this and uses static calls.

Can someone explain me how come if this is bad practise, Laravel being a classy framework?
