Re: Javascript is a plague
In my experience (dating back to 1994) take up of JavaScript was primarily driven by 'web designers' trying to compete with each other in producing show-off sites. The rise of the smart phone exacerbated the problem, as it became trendy to consider every web page as an 'app'. Now we find JavaScript doing utterly unnecessary things, frequently replacing the functionality of intentionally disabled HTML - for example, hyperlink targets coded as "#" and resolved only by JavaScript.
The fundamental problem here is that site user security is an externality to the web developer, who is often blindly using high level abstracted development tools that generate script-ridden pages, and who maybe never even examine the page source that has been created.
You only have to examine the source of web pages to see consistent patterns of coding that are unlikely to be the outcome of individual decisions. Most notable is the almost universal entire site map at the top of every page, presented as a massive JavaScript driven menu. Not only is this not navigable with scripting disabled, but it also thwarts users of screen readers, as they have to listen to the entire site map before getting to the interesting content of the page.
However it's clear that nobody really cares, even about accessibility. There are many comments from web developers on record to the effect that the proportion of users who disable JavaScript is so tiny that they don't count as potential customers, and an increasing number of sites are entirely inaccessible unless it's enabled. So tough on them - I take my business somewhere else.
