Ah. In those cases, it appears that the overwhelming majority (>= 95%) of developers explicitly agreed to the relicensing, with the remaining minority at least not objecting. That is still not assent by the remaining 5%, but was apparently sufficient for relicensing of the whole work in the relevant jurisdictions. In that context, the quote from the OpenSSL email appears to be well-phrased, as it really only assumes the absence of objections.
