Thanks for letting us know! We were not aware of these issues...

Being featured in our update is not something that any account pays for - we select an account from our own enhanced votes graph. I had some concerns about the account being a potential competitor, but decided that was not sufficient reason to not feature them.

It sounds like I should have followed my misgivings and researched further on how their VP is actually spent before featuring them.

Edit: I read the linked post, and while we have no issue with your side-by-side comparison, I do have concerns about this sentence:

There is no other public delegation>upvote service on steemit that comes close to my current ROI.

I compared the STU for 500 SP delegated to @steembasicincome against your chart and our daily would currently be $0.1876 against your $0.18, but with the added benefit of not having to post everyday to get that reward. If you missed a day, it would stack and your next upvote would be bigger to make up for it.
You do have to be enrolled in @steembasicincome for 1 STEEM to receive the benefits of direct delegation.
