It's not the engineers at fault here but C-suits. Those who are out of touch or stuck up their arse within their own world. Believing their own delusional vision is it based on that they have a toddler who's four.

I'd say engineers are at fault for bugs and performance issues, as well as poor UX (not counting what's made to sell you something or collect your data)

It can be the engineers issue, sure. Hire the wrong crew and you're sunk. However, while I might be bias, what do you do when the higher-execs don't give you time / space to fix the bugs, performance issues? No one writes genius code from day one of a project.

I've had to aggressively pitch to execs who've totally ignored the fact that $app is vulnerable. Would result in fines and if we optimized it could be pushed to milk further money offering X feature. I was denied because it's a waste of time, cost and "didn't provide anything for the company".

After finally persuading them and getting the classic response of "Oh!, why didn't you say so" three weeks later was fired for making the company waste money. This wasn't a small company in an industrial park.

Ever since I've turned down jobs that smell like toxicity. You can sort of see the companies stink when you enter reception.
