Does viewing require input format permission check?

It's a big strange that the viewing of the gcal event needs a filter_access check. How would any user actually use the selected input format to simply view the gcal events block?

This is a simple patch to remove the filter_access() call from the display function.

After removal of the filter_access check, the block will display to everyone with whatever input filter was selected without the need to check if they have editing access to that filter or not, which it should never care about.
