I think their anger is justified. Yes there's not a lot that individual engineers can do to help, but a big part of the problem is that they don't even understand the people they're "helping".

These tech gadgets are the annoying experience we've all had of someone taking a look at a problem from the outside and proposing unhelpful "solutions" that won't work because they don't fully understand it.

It reminds me of conversations I've had with people who suffer from insomnia. They say that everyone has some suggestion to just try melatonin, or not use screens before bed, or whatever. As though they haven't tried these things.

Yes they're just trying to be helpful, but it comes off as patronizing.
