So we should be against something that makes all sites faster... because big companies care more about their sites being fast? That just seems like spite to me.
If anything, smaller sites have more to gain from HTTP/2 and HTTP/3 than the likes of Google. For example:
- Both HTTP/2 and HTTP/3 seek to reduce the number of round trips, mitigating latency between the user and the server. Now, from Google's perspective, the "server" is the nearest load balancer in a globally distributed network, which is probably geographically close to wherever the user is. Thus, users with good Internet connections typically have low enough latency for the improvements not to matter much. But Google still cares about latency because of users with poor internet connections – such as anyone on a cell network in a spotty coverage area. Well, poor connections affect all sites equally. But small sites tend to not be fully distributed; they probably only have a single origin server for application logic, and perhaps a single server period, if they're not using a CDN. That means a fixed geographic location, which will have higher latency to users farther away even if they have a good connection – thus more benefit from latency mitigation.
- QUIC can send stream data in the first packet sent to the server, without having to go through a SYN/ACK handshake first. TCP Fast Open lets plain old TCP do the same thing – but only when connecting to a server you've seen in the recent past (and retrieved an authentication tag from). Thus, QUIC is faster when connecting to a server for the first time – which affects smaller sites a lot more than Google.
