They list Intel's contribution extensively in the post. I'm not sure why you'd assume they are trying to deceive anyone.
> Intel has been contributing to Chakra, the JavaScript engine for Microsoft Edge
> Some examples of Intel’s direct contributions to Chakra’s JIT compiler include better instruction selection and scheduling.
> [they] also helped us identify opportunities of missed redundant instruction elimination, and inline overhead reduction.
> Intel engineers are collaborating with us closely to implement Single Instruction Multiple Data (SIMD) [1], a future ECMAScript proposal, in Chakra
> Intel recently contributed an optimization to improve navigation (load) time for pages containing several inline elements, optimizations to reduce DOM parse times for text-area elements, and participated in investigations and root cause analysis to improve page load/response times
