From their blog post
"We strive to limit actions taken to only those necessary to comply with local laws. Our response should not have impacted users outside of mainland China. We made two mistakes:
We suspended or terminated the host accounts, one in Hong Kong SAR and two in the U.S. We have reinstated these three host accounts.
We shut down the meetings instead of blocking the participants by country. We currently do not have the capability to block participants by country. We could have anticipated this need. While there would have been significant repercussions, we also could have kept the meetings running."
