What kind of statement is that in that if you are not going to eat OU, you will not have a lot to eat?
It’s a statement of practicality.
I expect that if the OP feels that the OU is unreliable, he should not only not eat OU products, but not eat anything/anywhere that relies on OU ingredients. This includes just about every restaurant and other kosher eating establishment in the US, as well as many food manufacturers whose mashgichim provide them with a list of approved products to use (most of which are probably OU certified).
If the OP truly feels this way, I expect him to do due diligence into every product before he buys it to determine if it contains any OU-supervised products. I also expect him to ensure before he goes anywhere to eat that they do not allow any OU products in their kitchens.
Good luck.
