So? If what is claimed to be true is true, maybe Apple, Mozilla, and Microsoft won't implement it - and that would be a big deal to the alleged nefarious plot. But, that won't happen if no one speaks up. That is, of course, if this isn't just nonsense speculation.
This is just conspiracy theory nonsense. If QUIC has such a flaw, it has an open spec and you are free to go find it and point it out.
