Mercedes exit from F1?

Hello F1 fans, after all the turbulence in the last and this season and in view of the current economic crisis, the question arises me whether a further engagement of Mercedes in the F1 or in motorsport (DTM etc.) makes any sense at all. Since I am also interested in your opinions, I have prepared a survey here. Comments on the vote are welcome. mfg invisible_ghost ps: with point 5 of the vote it is meant that Mercedes separates from McLaren and continues as an independent team.
