Well yes but quantum computing and silicon photonics are not entirely separate fields. Photonic computing can still enable introduction of algorithms that utilise quantum properties.
I would agree that some claims are lies or misguided, however yes with the right algorithmic processes, these devices can affect current security of cryptography one day. That doesn't mean their work was worthless but like everything, things progress. It's not obsolete, it's been built on.
The industry shouldn't be fabricating claims but the industry that is honest of which there are many, do not need to protect other industries. Fabrication happens in every industry.
Tech is only obsolete if you aren't inventive of how to repurpose it.
