This sounds like a misinterpretation. The OSA is primarily about making online service providers responsible for age verification, if they supply adult content. No different in principle from having to prove one's age to buy cigarettes, alcohol, knives, etc.
No-one says "cigarettes are censored!", because, obviously, they're not. Same for adult content online. It can still be accessed, as long as proof of age is provided.
