I have been studying Javascript for a while now and I found that JS is what most modern websites use (probably less than PHP though), and is also the inner language of most browser engines. Everything related to Javascript is defined by ECMA, which is a group of companies that set the standard and upgrades of the language. These companies are obviously the big tech https://www.ecma-international.org/about-ecma/organisation/. My question is: How messed up is the internet because of this? I am curious about how different the internet and web browsing in general would be without ECMA or with ECMA but not controlled by this giants, and if instead was just a community of devs, users, etc (like bitcoin).
I don't think the ECMA definition of JavaScript has much of an effect on the shape of the internet. Also to be clear browser engines are not internally implemented in JavaScript, but in languages like C++.
The Web Platform specs, that's a different story though - those have 100% effect on the shape of the Internet with multiple standardization organizations (the main one being W3C). See https://developer.mozilla.org/en-US/docs/Learn/Getting_started_with_the_web/The_web_and_web_standards
