I live in a first-world country, I do have an Android phone, but I'm always out of internal storage and need to delete apps. Most people in my friends/family circle are in the same situation. So even if we have Android, services based exclusively on mobile apps have an accessibility problem for us. I suppose this problem will be larger in places like Burma, where smartphones will be cheaper and older on average.

Most devices in the developing world have micro SD slots.

Mine also has one, but the apps just don't want to go there. In fact, some apps like spotify insist on storing even their data in the internal storage. So I have a full internal storage and an almost empty big SD card. I know these things can be solvable via rooting, but most people doesn't root.

I was really frustrated by this for a while. There were some instructions on the Spotify website about re-installing the app when the SD card was plugged in, but it never seemed to work for me.

Recently they added the ability to explicitly choose where you want to store your offline data.
