I've never seen a $300 one but I've seen $70 ones. I don't think they're nefarious in that sense, but these boxes are usually scams.

They come preloaded with a pirate iptv service that only works for 1-2 months then they ask you to pay something like $70/year to keep watching. There's tons of providers for these IPTV services so bundling them with the boxes is a way to make it easy to access while gaining subscriptions, you can just buy a cheap android TV box yourself, install the apk and get a cheaper IPTV provider.

Most of these boxes/providers don't last more than a couple years as authorities tend to go after them when they get too big. My dad uses them to watch portuguese TV--it would be impossible to watch certain channels outside the country otherwise--and in the past 10 years he changed provider 3-4 times.
