> Somewhere, someone decided that you must build your websites a certain way, or you're doing it wrong™ and some people have gone as far as to actually wish harm on people for the tools they decided to use to build their websites.

When was this ever not true? I remember people who wrote HTML by hand deriding those who used WYSIWYG editors 25 years ago, though perhaps not wishing them harm.

More hated than those editors were proprietary plugins like Flash, Java, Microsoft's not quite compatible version of Java, ActiveX, and the like. Some sites were unusable without a very specific configuration of client software, almost certainly requiring Windows. They were usually painfully bandwidth-intensive as well in an era when the average connection was about 0.05 Mbps.
