I am okay with manual switches.
The point is. Regardless to the origin of this malfunction. (Which is so far attributed to the pilots inability to follow checklist and they nonexistent response to the warning lights)
This was a sensor malfunction! Something literally stopped working.
(Moreover, poisoning other instruments with misleading data flow )
This can't be right.
This is critical to flight instrument and you can easily theorize a lot of situation in which the clear knowledge about Pitot tubes malfunction couldn't be substituted by "your speed is messed up" warning.
