Right, well, the solution is to check the S1, because it, and nothing else, controls:

The Class A common stock is non-voting and is not entitled to any votes on any matter that is submitted to a vote of our stockholders, except as required by Delaware law. Delaware law would permit holders of Class A common stock to vote, with one vote per share, on a matter if we were to:

 	• 

change the par value of the common stock; or

 	• 

amend our certificate of incorporation to alter the powers, preferences, or special rights of the common stock as a whole in a way that would adversely affect the holders of our Class A common stock.

In addition, Delaware law would permit holders of Class A common stock to vote separately, as a single class, if an amendment of our certificate of incorporation would adversely affect them by altering the powers, preferences, or special rights of the Class A common stock, but not the Class B common stock or Class C common stock. As a result, in these limited instances, the holders of a majority of the Class A common stock could defeat any amendment to our certificate of incorporation. For example, if a proposed amendment of our certificate of incorporation provided for the Class A common stock to rank junior to the Class B common stock and Class C common stock with respect to (i) any dividend or distribution, (ii) the distribution of proceeds were we to be acquired, or (iii) any other right, Delaware law would require the vote of the Class A common stock, with each share of Class A common stock entitled to one vote per share. In this instance, the holders of a majority of Class A common stock could defeat that amendment to our certificate of incorporation. Moreover, if an amendment to our certificate of incorporation would alter the powers, preferences, or special rights of the Class A common stock and either the Class B common Stock or the Class C common stock in a way that would affect them adversely compared to the unaffected class, Delaware law would permit the holders of Class A common stock to vote with the other adversely affected class of common stock together as a single class. For example, if a proposed amendment to our certificate of incorporation provided for the Class A common stock and Class B common stock to rank junior to the Class C common stock with respect to (i) any dividend or distribution, (ii) the distribution of proceeds were we to be acquired, or (iii) any other right, Delaware law would require the vote of the Class A common stock and Class B common stock voting together as a single class, with each share of Class A common stock and Class B common stock entitled to one vote per share. In this instance, the holders of a majority of the Class A common stock and Class B common stock, voting together as a single class, could defeat that amendment to our certificate of incorporation.

So, yes, the class is called "non-voting" but, as I point out, they still do have powers to vote. Just very limited ones. However, I am perfectly willing to admit that you do have a point that this is literally as de minimis as it gets.

This is distinctly unusual. But it is still not zero voting power - just literally as close as delaware law allows.
