Very briefly, 'Ecclesia Dei' encouraged bishops to make 'a wide and generous application' of permission to use the 1962 Missal, if those requesting it accepted the validity of the Roman Missal (1970). This would be restricted to the times and places determined by the bishop.

'Summorum Pontificum' (2007) went a good deal further, stating that priests were no longer obliged to ask special permission of their bishop to offer the traditional liturgy. They could just do it without restriction.

Correct. And Cardinal Bergoglio never obeyed the the latter, Summorum Pontificum, in his archdiocese. As a matter of fact, he punished priests who tried to exercise their rights.
