You say that there is wrong information but I don't see you providing examples with sources.
I will agree somewhat with your soldering vs brazing statement, as that's really a matter of temperature over anything else that defines them.
Your stated logic for why crimps are used instead of soldering is also objectively false. It's not about saving money or worker toxicity.
If it was about toxicity, you wouldn't have whole factories running wave soldering machines with gallons of hot liquid solder constantly flowing.
If it was about money you wouldn't see strict engineering standards which outright forbid the practice citing mechanical failure as the chief reason.
Further to the point about the quality of a soldered joint, solder has much higher electrical resistance than copper does. It's inherently worse than a good crimp for that alone.
Please provide your evidence.
Here's mine:
EN 16602-70-26 (crimping of high reliability electrical connections for spacecraft)
A literal NASA document.
First line:
"Crimping is an efficient and highly reliable method to assemble and terminate conductors, and
typically provides a stronger, more reliable termination method than that achieved by soldering."
Interestingly it also forbids crimping tinned wires, which is the only place I've seen that, though it might be in other documents and I've missed it.
NEC allows soldering in *some* circumstances and forbids it in others. When it does mention anything about why, iirc, it's again for mechanical reasons.
