I really don't think it would be accurate to say they were created with that intention, even if you're very cynical about the matter. Just simply from a historical perspective, I really don't think Jesus or Buddha had any intention of creating controlling religions.
And on that note, I don't really think think religions are necessarily controlling. Don't get me wrong, every religion, even the "less controlling ones", have historical examples of being used that way, but I think thats mostly an effect of institutionalization. Most things become pretty corrupt when they meet institutionalization.
Still, that wouldn't mean they were created to control, just that they got *co-opted for control*. Which many good things have, unfortunately.
But also, I feel like when most people make sweeping statements like this, they are usually only familiar with Christianity (particularly American protestantism), maybe a bit of Islam. There are so many other religions though, historically and today. And even those two religions are not monolithic.
Quakers aren't particularly controlling, Alevi Muslims are not only not controlling, they're actively a source for progress and liberation in Turkey.
So yeah, even if one is super cynical about religion, I don't think what you're saying is very accurate.
