And everyone else is well within their rights to call their decision what they want. So what exactly is the point of stating this?

What's your point here? No one is saying reddit is not allowed to make this decision, people are arguing that it was a stupid decision. Its absolutely a company right to shit on their bed and hurt their customers, just as much as it is for said consumers to respond and criticise.

Indeed, they are within their rights to make decisions, including questionable[1] ones. Which is what the conversation is about – not if they can be doing this, but if they should be doing this.

That applies to consumers as well. Killing off a product that added value for people is going to make them upset. Are we supposed to be praising Reddit in your view?
