While I agree that it was a stupid decision, it may be to Mercedes benefit in the end:

- They ended up with a 1-3 (40 points) instead of a 1-2 (43 points). So they lost 3 constructors points. The way things are going this season that shouldn't matter.

- People aren't saying 'Mercedes is crap', they're saying 'Hamilton's race engineer is crap.' So that shouldn't really hurt Mercedes, only one of its employees.

- The headlines might read 'German driver wins 3rd consecutive Monaco GP in a Mercedes' instead of 'Hamilton wins 1st Monaco GP'. This could actually be a plus for Mercedes.

- Rosberg winning the race closed the gap between him and Hamilton by 17 points, making the drivers championship more interesting. The battle for the WDC this year will most certainly be between the two Mercedes drivers, so the longer it stays close and interesting - the better it is for Mercedes.

- Lots of headlines and people talking about Mercedes because of this.

The overall losers in all of this are Hamilton and his race engineer. The winners would be Rosberg and Mercedes. I don't think Mercedes will be upset about that.
