というものでもない

というものでもない is used to downplay or challenge the assumption that a certain situation or outcome will occur. It conveys that something is not as certain or as straightforward as one might think, and that other factors could influence the result. It often follows a statement or expectation to indicate that it’s not necessarily the case. The nuance is more cautious than plain negation, suggesting that one should not jump to a conclusion based on appearances or general tendencies.
