I haven't forgotten the UPS 747F which went down in Dubai with Li-Ion batteries as the suspected cause, also the Asiana 747F which went down in similar circumstances. If these were passenger flights maybe Li-Ion batteries would be viewed differently.
Not necessarily. These Li-Ion batteries were carefully placed in secure blue boxes and monitored, which *should* have eliminated the earlier problems. They might have been viewed differently by the public, but I am not persuaded that the engineers and regulators would have acted any differently.
