Sealed for your protection

I opened a bottle of salsa yesterday and saw a familiar message. "Sealed for your protection". This message is puzzling for 2 reasons:

1. The use of these seals seems inconsistent. Sometimes, like on Gatorade Propel Sports Drinks, the seal seems like overkill since it also has the plastic wrap around the opening. Then on other products (I can't think of any, but I know I've noticed some), it seems like they should have a seal, and they don't.
   
2. Is it really sealed for the consumer's protection? I don't think so. In fact I think it is sealed because if someone were to slip something in my salsa and I got sick, I would sue the nuts off the company who made the product. So in reality it should say "Sealed for OUR protection so that you don't sue our nuts off if you get poisened" or something like that.
