> Please stop blaming the devs. You're laundering blame. Almost no detail of a web site or app is ever up to the devs alone. If a bridge engineer is asked to build a bridge that would collapse under its own weight, they will refuse. Why should it be different for software engineers?
It's a website and not a bridge. Based on the description given, it's not a critical website either. If it was, the requirements would have specified it must be built differently. You're not even arguing with me BTW. You're arguing against the entire premise of running a business. Priorities are not going to necessarily be what you value most.
On those sites you’re right: the approach was different, but not necessarily better. Tracking library bloat and marketing-driven design were reduced. But insane “security” constraints (e.g. “you have to stay on outdated revisions of this library” or “containers are not allowed on the backend, only bare metal”, no joke—constraints that led to significant increased security risk) and extremely user-hostile design practices increased, as well as there being an exceedingly long hurry-up-and-wait turnaround time for shipping important fixes/improvements.
Working on a safety/state-critical site isn’t a panacea, in other words.
