Storage is cheap but bandwidth is not guaranteed. Getting content from your server to my device is not necessarily fast. Making wrong assumptions about my device's environment makes for a poor experience for me.
if you cache well - you will absolutely use less bandwidth with an SPA.
Sure - that first load is going to be bigger, but literally every subsequent request will use less data.
I try to reward consistent and current customers - and I'm not selling a news article or a social media site...
Now - if you do things like attempt to refresh all of the cache often, then sure, you have some problems to deal with.

Tough shit? I go way out of my way to make sure that loads on bad lines (or no lines) don't interfere with my users. You could just as easily say "I'm on gigabit why is this app using my disk space? Making assumptions makes for a poor experience. WAAAH".
