Indeed, SVG is a bad standard because it is too complex. There is no 100%-compatible SVG editor (except notepad) - every vector graphic editor just supports its own subset of SVG, things get lost when transferring things between "SVG-supporting" editors. There are multiple ways to do the same thing in SVG - this makes it difficult to understand a SVG file created by someone else and it is very hard to return to a complex SVG file after few years and modify it. The complexity of SVG makes web browsers larger and more complex (hence less secure and slower). So, I disagree with the article. Keep away from SVG unless you really need it and maybe someone designs a simpler vector format for the web.
