While the actions were beneficial in this case, that argument would be more convincing if the spec itself weren't a constantly moving "Living standard" maintained by the exact same organisations that also develop the browsers. And even that spec is sometimes consciously broken in an "intervention".
That aside, your position is unrealistic: browsers regularly break non-spec conforming websites. They actually monitor such cases (telemetry) and try to work with popular websites to fix the issue before they ship the breaking update, but it's a tradeoff that is regularly made nonetheless.
