There’s a very big difference between kashrus issues in chutz loarerz and eretz yisroel. In eretz yisroel, anything besides water and salt that’s edible can have a multitude of kashrus problems and can be issurei deoraysoh. A reliable hashgocha isn’t just about shipping verification, ingredients and bishul akum (the biggest issues in American kashrus) – it’s a constant maze of preventing issues with terumos umaasros, shmitah, arlah, yoshon, and tons more – with little leniencies available.
Comparing triangle K to Israeli issues is way off.
