OSMF would not at all concede that the concerns were unfounded! After all, dropping CC-BY-SA would remain a possible response if its weaknesses are actually exploited some day in a manner that harms the project. Dual licensing simply means that we do not use this option *preemptively*, and this could easily be communicated as such. Until now, we were in a situation where we would have been helpless against legal abuses. With the copyright distributed among thousands of mappers and the data being bound to a single license, there was no way for us to respond to large-scale legal exploits to within a reasonable amount of time and without heavy data losses. OSMF has recognized this danger and made sure that - should the need arise - we will be able to respond quickly and in a meaningful way, thanks to CT and centralized licensing of the database as a whole. If we, in addition to the reasoning above, emphasize the other benefits of the new licensing situation (such as the clearer situation of attribution, the prevention of future data losses due to any licensing changes, etc.), it is easily apparent that we have gained a lot through the re-licensing efforts. Dual-licensing does hardly detract from that.
