It is a question of convenience, it is good to have it so people can use if they like, there are still majority who do not use it.

Depending you the number of users that people try to keep to cover it is not really easy to be everywhere. The reason why such autovotes were introduced is to attract investors with high return of curation %, because many Investors do not post but they receive the % from their curation back. We all complain why we do not have investors and this is a why to make them stay and invest more so that they see that return.

On other hand for smaller accounts it is also good, because they have Upvotes, actually it is win-win situation, in my opinion.
