A less malevolent interpretation could simply be that they're using AWS services to do whatever machine learning / algorithms for profile matching. It's very possible they aren't selling data, just sharing it with 3rd parties like AWS, Google Cloud, or whatever vendors they use for data processing / analysis. But I agree, if they have no intent on selling the data, the wording could be narrowed to make that more clear.
