We purchased a Chinese-made projector from Amazon, which was surprisingly inexpensive (~40 USD). Upon connecting it to the internet, it placed a constantly running feed of ads on the corner of the screen, even while movies were playing. There was no way to disable it either. Even though it's not a stick, it's a similar principle.
I mean, did you have to connect it to the internet though? Did it not just have a dp/hdmi port?
Upon connecting it to the internet…
I hesitate to blame the victim here, but why on earth would you do that? “$40 Chinese-made” didn’t give you pause?
I remember reading an analysis on one of those projectors; the author found a residential proxy running on their device. I would recommend keeping these things off the internet.
