Tobacco product advertisement has been forbidden for nearly thirty years. Crying that they are not involved anymore is... strange at least.

Alcohol advertisement has been partially forbidden in certain countries as well. Since WRC is global You can't expect involvement of a company which would need to remove its adverts for part of the events.

For the rest it's easy to say that some company was involved and isn't anymore and completely omit the opposite case - the companies which were never involved in the past but are now in. You can start with Toyota sponsors Microsoft or DMG Mori.
