What effect on MCU fan following after endgame

Fans reaction on retirment of main heros in endgame 

 We know in endgame our main hero like iron man, captain America ,black widow 

Die and there is no movie in future due to which fan s very upset and sad from marvel 

That was why the fan following was decreasing slowly if it can continud as that was day not far when marvel stay on his flop position

And the reasons which doing because of death of iron man

So that was my reaction on marvel

So what is your reaction guys please tell me
