They've memory-holed (i.e. deleted) their entire old blog, no? It's disappointing but I think it's a stretch to describe that as Orwellian (as the OP did). At some point they just discarded all their old content, it's not that much of a conspiracy.
The motivation is what matters for the folks calling it Orwellian.
If someone is deleting their posts because the facts don't align to the worldview of a religion, a political party, a corporation or some other powerful group, many people will be more concerned about that than if the posts had been deleted for more routine, functional business reasons.
Entirely possible they don't care for the page views. Don't get me wrong, I'm not defending it, I think it's a shame that interesting content like that gets pulled down but it's usually for boring corporate reasons (don't want to maintain the blog any more, they don't benefit from the pageviews) than conspiratorial Orwellian reasons.
I don't think it's a orwellian conspiracy, they make money running a dating website and took down some old blogs that suggested online dating is really pretty rigged not in your favor for guys (their paying customers). You don't need some men in the shadows to explain why they took that down
