Yes, it seems natural that the protesters would prefer Bitcoin so that their money is safe. But they can also prefer it for political reasons so that they are not using the currency of any specific country and support decentralization. The talks about a possible connection started back during summer. There were a few articles about it, and there was even a thread on Bitcointalk dedicated to this topic. But the article, like others mentioned, does not really settle the matter. It's unclear whether there's a direct connection or whether it's a significant volume to discuss at all.
