Am I misremembering? I vividly recall finding information with regards to this type of structure not being allowed (unsure if regulatory or stock exchange level) with these examples (Mark's majority, Page+Brin's majority, BRK A shares) last time I came across this, but now I come up empty-handed. So I'm unsure and don't have much time to dig in, maybe someone more knowledgeable comes by. Feels bad that I can't edit in a disclaimer to my previous comment, I don't want to parrot misinformation.
