Most of them don't have any reason to care whether or not most of us vote for them. You might get some responses from those below the 50 mark and a couple who are concerned about community votes, but for the most part there are a handful of people who's votes can move the witness list.
The witnesses do not answer to the community, they answer to the stake.
Thank you for your feedback @whatsup

And it is time for the downvote to end every time you comment objectively, as it is for you now it is time to clean it up. If I give you upvote they just go higher afterwards to make you invisible again. It is very bad behavior
It should be 3-5 votes per account, though that won't gain any support from the current group of witnesses because it could negatively effect them.
