Why limited export options?

I know Aero is in Beta form but I (along with many others) have repeatedly asked for more export options. Forcing end users to download Adobe Aero onto their devices is not a good decision. Most people I know can'r even install Aero on their phones because it is not compatible. Not everyone can afford the latest mobile phones. Not everyone uses Apple or Samsung neither. I've spent a lot of time creating an experience but it's a struggle to ask everyone to download Aero in order to view it. I am now in a position where I will have to consider buying a newer phone. I'm not due an upgrade until next year so I don't know how I'm going to pay for this.
