If "£300m damaging state property" isn't terrorism then other examples of it aren't either. That's the point. the purpose of proscribing groups isn't to comment on the morality of the cause, it's the actions.
Are you suggesting vandalism with paint caused £300m worth of damage? The British Forces should be thankful that a hole in their security was brought to their attention without doing worse damage.
