> Reddit is not beholden to to their users to the degree that those users probably believe. Nor are they beholden to some imagined ethos about being a place where all speech is protected.
You're right, but it doesn't matter whether they're "beholden" to it or not, they're the consumers and they're telling the market that they want a platform with transparency and where speech is protected. It's just supply and demand, so if there are signals that reddit isn't satisfying what its market demands, how exactly is reddit immune from your average market forces here? It's a popular site, sure, but so were digg and myspace. Just because users have certain expectations of a site, that the site itself may or may not have actually promised, does not make the site immune from competition.
So in reality, it's not so much about users feeling entitled to anything, it's that reddit seems to have been getting complacent about what it feels it needs to deliver to stay relevant to its content producers and power users (which are the main drivers of a site like that).
Companies can dictate how their services are used all they want, but that doesn't mean they have an automatic right to remain successful/profitable/relevant, especially if how they went about dictating their terms hurt their PR (whether reasonably or not).
