Why not? It's arbitrary anyways--as the article mentions the same place previously switched (which means if the Jews didn't like change they would still be on the time that everyone is now switching back to).
Christianity is actually split on which day to keep. Those that follow the Catholic Church (via canon 29 of the Council of Laodicea) worship on Lord's Day[1] (Sunday). Those that feel the church could not change the day of worship (e.g. Seventh Day Baptists) worship on the Sabbath (Saturday).
What's to follow? It's just a one-time change that makes a lot of sense given their location. They aren't permanently getting rid of Friday. Besides, Hebrew and Muslim calendars are lunar-based and I would imagine not affected by this.
