A lot of activists in China—or regular citizens who might be speaking out about something—also use western platforms. They use Twitter, mainly, but now we're seeing those accounts taken down and those people being detained for using Twitter inappropriately—or whatever the justification is. I don't know if there's something that western governments can do to highlight those cases when that happens.
The other thing would be that I think the Canadian embassy is pretty active on social media platforms in China, and they've done some things to highlight certain anniversaries and certain cases. I think that's a positive thing.
