I think everyone agrees that some rules for guests are fine, and some are silly. "No flash photography or leaning into aisles during the wedding procession" is a reasonable rule, "No taking photos when we're dancing and having fun" seems silly to me.

Just like a dress code for a wedding is fine, but if they said "also you need to wear blue cotton underwear" I'd think that was a bit inappropriate to require.
