I thought it was related to the article. Probably automatically matched by "google" tag or something like that.
After all, this is all related.
Lately, I've been messing with wifi and hostapd. I get massive maps images, and pictures of hotels in the first 1/2 of my respones. I presume "hostapd" is a close mistype to "hotel", and people are searching for high speed wifi, so they may be searching for 80211ac or some such. Or likely google just sees "wifi thing -> wifi", and now I'm apparently searching for "hotel wifi".
Great. I can't get anything meaningful, unless I add -hotel.
They've gone so overboard with loose context matches, that I can't imagine their ad placement has much value.
