I don't use Messenger at all (Speaking of which, WHY is it required now? No thanks, I'll downgrade my FB version), and since I regularly clean my system cache, I don't have to worry about space constraints. I don't see the need for videos on my phone since Youtube+Media Streaming services exist, and if I at all needed to say, watch a movie or anything of that sort, I would just...use my laptop. Games are a fair point but not too many ever take up more than 100MB anyway, unless you need to play every iteration of Chaos Rings at the same damn time. Photos are fair too, but I don't take enough photos on my phone to where I'm eating 2~GB of memory.
