>>How does it affect JetPack users?
Without a VPN you cannot connect to Jetpack. If you use the site stats module of Jetpack to track your site's traffic, that will not be affected (unless all your site's traffic originates from China, Turkey and Pakistan and those visitors are not on VPN).
But you will only be able to see the stats of your site once you have turned on your VPN, without it, you will have to accept that you're blocked from the "outside world".

As I am living in China, I have been dealing with these type of issues for a very long time already and you will find that although there almost always is a way around these blocks, you will have to ask yourself whether it really is worth it?

I'm almost 24/7 on VPN, but the reason why I need/want that certainly is not because wordpress.com is blocked. That is a just a nuisance at best.
