And this was Sophie Schmieg’s talk at a cryptography conference this month (they lead PQC migration efforts at Google) tracking migration efforts and urging folks to prioritize signature migrations in lieu of accelerated quantum timelines: https://westerbaan.name/~bas/rwpqc2026/sophie.pdf

> Is this market manipulation?

i think google is just a disgustingly large company lol, it's hard to talk about them "caring" about one thing but not another
