What will happen if China and the US reach some kind of agreement, and unlocking online US-services will be part of it?
AND when cloning physical goods (like phones, cars, clothes, shoes, whatever) -- you can export them, since people are willing to pay lower prices for clones. How can you export a Tumblr or a Twitter clone, when both are freemium?
How are these clones surviving? Do they generate revenue, when Tumblr, Twitter and Facebook can barely do it?
Something is not right about this picture ;)
If China and the US reach some kind of agreement - and the services were unlocked - there would already be enough of a market share for the existing clones to maintain control over that market. Future clones would still have a chance in succeeding as well depending on the race to localisation of the products in the local language and demographics.
On the Tumblr monetization front, TheStartupist[1] covers a good portion of their story. Checking Crunchbase[2] shows that they've gone through pretty large funding rounds, with their last one (D) at $30M the largest. I've been trolling Tumblr for the last year and half, and the only things I've been able to scrounge are the $9 Directory listing under your category of choice and the premium themes.
They're still growing massively, as all the cool kids congregate there to post their Instagram-faded pics of teenage angst, but are hemorrhaging money like Twitter. And like Twitter, advertising is viewed as pure evil[3] and not a viable solution to generate revenue. Twitter realized the inevitable and started Promoted Tweets recently, and Tumblr will have to do something similar soon as well. Maybe they make enough from the themes, but that seems a little quixotic.

I'm sure they will figure it out eventually, I'm just unsure whether they are going to have an easier time then this chinese clone(at least to the point where they will be pointing and laughing).
Lets not forget that tumblr has spent millions of dollars and years coming up with the mix of what makes tumblr work and it has been essentially copied wholesale, if this ends up working in a chinese market, thats a huge competitive advantage for the chinese clone, because they didn't have to spend any of that money or resources to begin with.
