And then, of course, browsers are themselves being likened to operating systems. Walled gardens, with no efficiency to speak of, with very little freedom, with too much leverage from the browser vendors. A perfect exploitation machine for keeping you within itself, all while it will do anything to harvest information about your activities, so it can show you some ads as soon as it can. An operating system alright. Yeah, just relax and no harm will come to you.

Moreover, browsers are not the right way to be using web anyway. See my thought on this in the Data-Supplied Web article.

he only advantage of building something in a web browser is that you can view websites right in them. If your task is not to display a webpage, or build a website, if CSS+HTML is not the limit of your imagination, then there's no reason to be building complex shit in the web browser! I can see hitching a web browser ride as a ubiquitous cross-platform graphical backend (over WebGL) if you are willing to deal with all the overhead and impact on speed. But with the libraries like SDL and Skia (which browsers use), that seems kind of pointless.
