I am from a time that mistrusts too much power in too few hands. A time that had strict limits on media ownership so as to prevent only select voices from shouting down and distorting the perceptions of the masses. I've seen the effects of those restrictions being loosened and then done away with. All the dire predictions of which largely coming to pass. I would simply hate for "Star Trek" becoming the latest example of history repeating itself.
Um, we're talking about a guy who makes movies, not the guy in charge of the studio/network/publishing house. Abrams making Star Trek and Star Wars is not going to turn him into Rupert Murdoch.
