Probably because implementing a full browser is quite a lot of work, and it wouldn't gain them anything. They're not designing these as nifty tech that gives you maximum usability, they're "money-making machines" that aim at making it easier for you to do further purchases online (movie and series rentals, games, and so on). Having a full browser on there would proably make it easier for consumers to access open content outside of the particular walled garden the device gives you access to, which of course wouldn't make a lot of business sense.
