After doing this professionally for 20 years I've found that clients don't care what language, framework, hosting provider, etc you use to solve their problems. They don't care about your code quality, they don't care about your CI pipeline or any of that shit. They care if you have solved their problem for them, and that's it.
I continue to be surprised by how little impact gigantic hacks seem to have on large companies. Countless media reports of deep intrusions, stock market valuations not dented in the long term.
Until giant hacks result in actual pain being experienced by the leaders of these companies in the form of jail time and/or fines that aren't rounding errors on the balance sheet, no one will care.
