The original article is no longer on Medium.
Anyway, as was discussed in the Reddit thread, our Sponsored Stories are clearly marked as such. They're more like a textual ad up to 500 words long. They are not published with regular news, and don't even go into the regular mix of news stories. So whatever, if you call that bribing, even though it happens completely above-board, then your definition of bribing is clearly not in line with the actual definition, which describes something more behind-the-scenes and sinister.
Thank you for addressing it. Keep writing. You specifically and coin fire are my sources right now. I like your writing moreso than most on the site you write for and will follow you to other sites if you ever switch.
