1) The idea of the web is that the boundary between consumer and creator is very blurred. It is a world-wide, distributed environment. Making the tool you consume also the tool to create empowers a lot of people. Consider yourself a budding publisher on a very bad connection in an emerging country: you download a browser to surf the web, and that one now also enables you to create something for it. Downloading xCode or Android Studio would take ages. For developers, this is also an advantage: you use the same browser your end users have. In the past developer add-ons interfered with the rendering of the page and the performance of the browser. This gave you false results. 2) Whilst devtools make any browser bigger in initial file size (including Chrome and IE), it is not a large part of the main download (fonts are actually a huge one). The performance hit is to the overall computation (much like a standalone tool would) but isn't impeding on the browser performance itself.

Not really comparable. Composer was a WYSIWYG editor for web pages; the WebIDE is an editor, but more importantly it manages the packaging and creation of manifest files of apps for you. I started with Composer and the output was so awful that I learned HTML instead. This doesn't hide any code from you or generates things you don't want. The templates of the apps are maintained by the community on GitHub.
