It's because they want to reap the benefits of a social platform without actually participating in a social aspects of said platform. If by they you mean Google then I agree. Google reaps the benefits, to the tune of billions, while deflecting as much accountability as possible. Google's entire m.o. is to build enormous scale through software automation without providing any human-level support to its users. Large changes (like the removal of dislike counts) are made only under pressure from powerful groups, unless Google deems such changes to be profitable.
