That's actually a misrepresentation. TCP actually works pretty well on crowded networks; a major feature of TCP is to avoid congestion collapse. It doesn't always fully saturate busy/lossy networks, which is an area for improvement, but it's not the same as congestion collapse. TCP BBR is an attempt to fix TCP congestion control so it can saturate busy/lossy networks more reliably. That doesn't require QUIC.
