Because he comes from an era when there was next to no official yuri, everyone was a scrapfag and we liked insisting that our favorite couple is actually “official” and everything else is crack. He is called Ack because that’s what he actually hates, crack. Poly is just what people already used to trigger him more than a decade ago because it’s the same but even more “degenerate” and “degrading the characters”. Mostly Madoka stuff (doujins especially) since that has the most clear cut quasi canon pairings, but I think what truly broke his brain is that he was a Tsubasa Chris shipper (and hence flamed everyone who shipped Tsubasa Maria) before Symphogear sidelined that pairing to go all in on Tsubasa Maria.
The irony is that this position is completely untenable in today’s yuri filled world. He’s a relic of a bygone world still fighting his own personal wind mills: Bad shippers.
