The Americans have always been petty like this. They try to squeeze everything they've got in the form of advertisements.
But stuff like this is more important:
With the Indian Navy’s eleven P-8Is already in service, and an additional six to be procured; the Indian Navy will also be inducting other ‘US-Origin’ helicopters and unmanned systems. The Super Hornet Block III on offer to the Indian Navy will come with advanced network architecture that will provide opportunities to interface seamlessly with other U.S origin assets including Indian Navy’s P-8Is.
Full interoperability with the P-8Is, Sea Guardians and Tritons in the future is a huge advantage.
...both variants are carrier compatible to perform the full range of combat missions and can fully operate from the carrier deck.
Of course, the two-seat carrier compatibility.
...collaboration opportunities between the two navies for carrier integration, training, technology transfer, and so much more.
"...and so much more" is pretty much their biggest selling point. Unlike the IAF, the IN is going to be operating with very limited capability until 2040 at least.
The SH has far too many advantages for the IN even if the Rafale ends up with better performance and avionics.
