We do not downrank based on perf tests, but if we did, your bogus tu quoque would need us also to be Google-sized monopoly or market superpower pushing our own AMP analogue that assimilates such “better performing” content into our servers, the better to surveil, control, and monetize.
As we don’t propose any such AMP-analogue, and we don’t perf-rank, your selective “you might do it too!” response falls flat.
