The article is making an a public accusation: a lot of spying is happening, and they are naming some of the (in their opinion) responsible parties. Changing that to a title that only indicates the general subject of the discussion ("location data marketplace") obscures the article's thesis: "Your smartphone is probably sending your precise location to companies right now." (which is just a more detailed way of saying "smartphones are spies")
[regardless, it's your house, use whatever titles you want]
The definition of a better title on HN, btw, is: more accurate and neutral, and preferably using representative language from the article.
Nice way to deflect blame, just how many location tracking companies is YC invested in?
"Deflecting blame" doesn't enter into it (what does that even mean in this case?) and the answer to your cheap shot about YC is zero, as far as I know.
HN is a leading place for discussing privacy and surveillance; it has been for years; this article is obviously on topic here. We just want to avoid shitty internet threads. This one is already filling with "fuck you", "data rapers", and other pearls.
Since the article title is baity, we changed it in accordance with the HN guidelines (https://news.ycombinator.com/newsguidelines.html). If anyone suggests a better title, we can change it again.
