As of now, the historical relationships are no longer shown by default in the spiderweb.
You can, however, add these relationships again by clicking the "Historic" button:
Until now, all available (direct) relationships were always shown in the initial spiderweb of a company or person.
But as more and more information becomes available, it has become apparent that these initial spiderwebs gradually became larger and sometimes more cluttered.
That's why we have chosen to no longer show the historical relationships by default.
