Kosher meat in today's day and age is a business, whomever gives the hechsher and hires the shochtim is a different story. I'm sure some meat operations exist solely to provide a higher standard in kashrut and some in quality and some both (love bakar)
Maybe some stam places too are just a business, it's a business like selling daled minim or kaparos, few do it l'shem shamayim. That's why a guy who is passionate about mivtzoim would be angered.
Are the cheap daled minim mivtzoim / chinuch sets kosher ?
