Agree, I send millions of Push Notifications via Parse and I am also quite worried. I love their interface and documentation so I really don't want to switch.
Is it really not obvious? Parse doesn't overlap with Facebook's core goals and that frequently means somewhere down the road "business as usual" means "you have 60 days to GTFO". There's also not wanting Facebook to have access to your data or just plain not wanting to do business with Facebook (I fall under that category, a FB buyout or partnership is the fastest way to get me to stop using a service).
