Who spent a lot on their E-bike? Was it worth it?

I'd really like to see that article. In my experience pedals or crank arms fall off for a reason, and in the vast majority of cases it is not due to cheap parts, it is due to improper assembly.
It's amongst the giant section, an owner of a 2017 who posted in several different threads because his pedal fell out (yes, HE attached the pedals. )

There is a common misconception that because of the way pedals are threaded, that they are self-tightening. While this is true, in practice, I have seen hundreds of crank arms stripped out because the pedals were never tightened with the proper amount of torque during assembly. If a pedal is not tightened down enough, it rocks in the threads, chewing up the softer aluminum of the crank arm, until it eventually it falls off.

This is an experience I had which seems appropriate here:
I was riding a remote section of trail a few years ago and came up on a woman limping and walking her Cannondale Scalpel-SI. The pedal bearings had fallen out on BOTH sides within a mile of each other and the pedals came off the studs. She was forced to pedal using just the studs until it became too painful. The bike was less than a year old and had been purchased new at her local LBS. The studs were tight on the crank arms and had been installed correctly. It was a part failure on a fairly new rather expensive bike.
My truck was nearby so I offered to take her and the bike to the nearest shop. The nearest LBS was 40 miles away so instead, I removed the broken pedal studs from her bike and replaced them with the pedals off my spare bike. I learned a long time ago that a pedal wrench is a handy thing to carry in my truck tool kit.

Well, I found the article, it's right here on EBR.. https://electricbikereview.com/foru...tions-on-giant-electric-mountain-bikes.13976/
