Take a look at who owns The Guardian:

  https://en.wikipedia.org/wiki/Scott_Trust

In 1992, the Trust identified its central objective as being the following:

- To secure the financial and editorial independence of The Guardian in perpetuity: as a quality national newspaper without party affiliation; remaining faithful to liberal tradition; as a profit-seeking enterprise managed in an efficient and cost-effective manner.

The Trust sees its main functions as being the following:

- To secure the Trust's own continuity by renewing its membership and by dealing with threats to its existence;

- To monitor the organisation, financial management and overall strategy of the Group, holding the board accountable for its performance;

- To appoint and 'in extreme circumstances' to dismiss the editors of The Guardian and The Observer,

- To act as a 'court of appeal' in the event of any dispute between the editorial and managerial sides of the operation.
