here is a secret, Twizzlers does not change the formula on the day the Hemish Sticker comes into the factory, Its the same formula every day.
We are not talking about Twizzlers vs some Hemish Brand where the ingridiants might be diffent. We are talking about the same exact twizzlers .
If the Rav of the 2nd and 3rd Hashgcha has a question and was really doing things Lesham Shamayim,, He would just tell the original Hashchagha the problem.
Funny thing is there is a Halacha that if a Bagel Store opens, you cannot open another Bagel store next door, however if the Bagel Store gets a Hashgha, another Hashgha has the right to invade that territory and take away business
