46Therefore, first, the retention of traffic and location data for policing purposes is liable, in itself, to infringe the right to respect for communications, enshrined in Article 7 of the Charter, and to deter users of electronic communications systems from exercising their freedom of expression, guaranteed in Article 11 of the Charter, effects that are all the more serious given the quantity and breadth of data retained. Second, in view of the significant quantity of traffic and location data that may be continuously retained under a general and indiscriminate retention measure, as well as the sensitive nature of the information that may be gleaned from those data, the mere retention of such data by providers of electronic communications services entails a risk of abuse and unlawful access (see, to that effect, judgment of 6 October 2020, La Quadrature du Net and Others, C‑511/18, C‑512/18 and C‑520/18, EU:C:2020:791, paragraphs 118 and 119 and the case-law cited).
