FHE can be made IND-CCA secure in practice (i.e. for specific systems), please stop spreading misinformation. It's impossible in the general case for obvious reasons. Also, TFA isn't about FHE, it's about iO.
I know and have worked with the organizers of RWC and they've done a lot of the kind of work that you're dismissing here (which would be like telling Diffie and Hellman to piss off in the 70s because public-key crypto isn't IND-CCA2 secure without additional assumptions).
