It's understandable. Image hosting bloats costs quite a bit. It also introduces new issues with the law as the server admin can't allow illegal pictures on it. Offloading that onto a separate image host removes both issues with only minor downsides.
I'd much rather kbin focus on long-term posting stability than worry about image hosting. If it gets big, then we can think about it. Reddit went without image hosting for years though.
They gave a fight. If Reddit had just been silent, I bet most of the subs would be open now. Instead, Reddit has fought for every inch and in turn created an enemy to rally against. I was initially bummed and left to support the blackout and figured I'd just reduce my Reddit usage. With how nasty Reddit has acted though, I'm avoiding them as aggressively as possible now.
