you can outsource esp32 developement to india just fine. the fact that someone decides to use overpowered hardware so he can develop crapware is independent of where the crapware is developed
An ESP is a chip, not an SBC. So then you have to pick an off the shelf SBC from a different supplier which is either (a) hobby grade, see OP or (b) much more expensive or (c): you have to do your own electrical engineering, component selection, BOM, PCB layout, PCB manufacture, assembly, deal with a contract manufacturer - do EVT, DVT and PVT - ramp production, test/validate, package, stock and distribute the units. (c) is going to delay you 6-12 months.
We also don't know anything about the quality of the software running on those devices. I've seen some awful crimes against computers committed in embedded software - and I've seen some pretty well written software on more capable machines. And v.v. of course.
