The reason disposables are so popular in the US is the FDA banned any flavored cartridges, which doesn't include disposables. The immense battery waste is a direct result of a relatively new law.
The other reason is kids.
Kids don't have to hide proof of their consumption in their bedroom (well at least until they are hooked enough they can't spend a night without vaping). They buy, consume and throw away before reaching home.
The other reason is regulatory arbitrage -- the disposal vapes are often illegal products that circumvent laws in general.
I seriously wonder how it's even feasible for these things to be profitable.

Wait, what? Where's the sense in that?

That doesn't explain why vapes are so rife elsewhere, particularly the UK. They're popular because, as the FT described, they're the ultimate product. Cool, cheap and addictive.
