A random post on hacker news isn't going to make a dent in TP-Link's camera marketshare positive or negative. If the GP really has bad motives they wouldn't really accomplish anything with that. But I doubt they do. I use these cams myself too. They're ok if you limit their internet access. I limit all my TP-Link stuff anyway since they suddenly removed local access for their switched power plugs in an auto firmware update.
It's not the best company but they're cheap.
