People are making the right noises to show they don't approve, but contracts exist to ensure that the race is put on, and that the teams attend.
It's not up to the teams or Bernie if the race goes ahead or not, it is up to the organisers. Bernie stated this a couple of days ago.
Because the race was cancelled last year, they really don't want to cancel it again, because it would mean that it cannot simply be re-added for next year (some rule to do with 2 cancellations in a row), this would not be good considering they have a contract until 2016.
Also, it was announced today that some golf event is going ahead. If it's safe enough for golf, then it must be safe enough for F1.
