The same people who are downvoting you, I guess. I'm not really sure what the objection is but they are very consistent. I've actually wondered if someone set up some bots to downvote all the MBFC bot posts for some reason.
They have not. I just did some analysis of it, and there is one person whose account has downvoted almost every comment that the bot has left. They have around a thousand other votes, so it's unlikely to be a single-issue votebot account, but they also have no posts or comments, which is suspect. It seems plausible that there's something mechanical going on which might be concerning. On the other hand, it's only one person. There is one other person who has given so many downvotes to the bot that it's suspicious, also.
Aside from those two accounts, it all looks like real downvotes. There are accounts which have given hundreds of downvotes to the bot, but they're all recognizable as highly active real accounts, so it makes sense that they would give mass downvotes to the bot.
People just don't like the bot. Have you considered listening to the pretty extensive explanations they've given in this comments section as to why?

I was just entertaining a notion as I lack the skills to do an analysis like you did.
As for reading the other comments here, I have read them now, and they are interesting, but when I first commented, there were no other comments here and the post stood at -3.
Reasonable. I wasn't trying to jump down your throat about it. I was a little annoyed at the comments which are positing some sort of fantasy scenario where the bot is useful, but where people hate it for irrational reasons. But yours was a reasonable question, definitely, in particular because for at least one account, it looks like what you described is exactly what's happening.
