Yes. Yes they should, but the ability to fool an umpire helps win ball games and that is more important than any notion of fair play. As a result it is valued highly, the ethics of the thing is incidental.
There was no framing here though. Just Molina celebrating was enough to fool that blue electric donkey bottom biter masquerading as an umpire.
It was a rhetorical question but the whole thing is a sham. The dimwits behind the plate will be replaced by technology soon enough.
