The need for 5 open slots to sortie during events is for the sake of players, as each sortie consisted of at most 5 battles each with potential drop (not including more battles with Supply Ship), a player nightmare is when he/she realized why the fxxk there is no drop after S victory at the boss node, only to realize later that the slot is full, so that rule is to prevent that.

I'd be lying if there is zero conspiracy by dev but tell me which free game/app that are without conspiracy, many got their income from ads, in-game purchase, DLC, data mining, private informations, some even are malware like keylogger, while some free apps are experimental or to make a name for their bigger projects. You use them by agreeing with their business model, or aware of the risks. Of course there are free apps not asking for any profit.
