Of course you can't expect someone who just put something online as a hobby project to take much responsibility. But to ask some basic security/reliability from companies, foundations etc... Shouldn't that just be normal?
These can be quite intense (but, to be fair there's a ton of dross, there, as well). Probably best to avoid the broad brush.
These websites and applications can still have vast security implications depending on what kind of data is being collected.
The advertising industry has done security a huge disfavor by collecting every bit of data they can about everyones actions all the time. Adding some ad library to your website or app now could turn it into a full time tracking device. And phone manufactures like Google don't want this to change as the more information they get, the more ads they can stuff in your face.
This is only about safety. As i told to my coleagues in a former workplace: Safety first (that was one of company's mottos), quality second.
However the software has a terrible label placement algorithm that happily switches around the labels of adjacent elements. And it does so without notice after some changes to the model. That is behavior that can lead to pretty dangerous mistakes.
The reply of the software company: you have to check it anyway. That is why you get paid, right?
For SW ? No way. For electronic components, yes, for mechanical components, yes, but not for software. It is not cool. Fixing bugs is much, much harder than modifying UI elements (hello Google, Microsoft) with every release.
