these lamps are more sophisticated and cost more to make

Actually, they're simpler than a lot of other LED lamps, because they're not dimmable and use only a capacitor to limit current followed by a small post-regulator.

The driving electronics often fails before the LEDs, but they've minimised that with these.

Because they're under-driven, they actually need considerably more (typically four times as many) light emitters than a cheaper alternative, and those cost money. It's true that a capacitive dropper is a cheap way to make LED lamps work, but that's how the LED lamps you're offered in a typical store today already work, so doing that isn't saving them money over competitors, and since it's a long-life product they didn't skimp on the power supply design, check this Big Clive video for example:

I find a regular supply of cheap LED bulbs with that issue in the bin.. They really should put out a stupid modular model so you can swap the circuit for 1$
