Here’s the deal:
Hechsherim are not only about the strict Kashrus of the food. Establishments are routinely refused hechsherim due to non food related issues such as the lack of tznius of their wait staff or even their name.
If a restaurant having non tznius servers is reason enough to not give the place a hechsher then torturing animals being used for food should be enough of a reason to refuse a hechsher. If it isn’t then is says something (probably negative) about our priorities.
