Streaming modules, Apache server, Nginx server are also free software, Why do you use it?
Software or tool can be free, but other case is how to use it properly.
Whatever, in case of my script it's not a script you mention, so most of your comments are false.
It's not working all the time, but mostly does the job once only. Later make use of simple cache.
This is nonsense to talk of slower performance. Minification main goal is to speed up read process. Combining few files is to limit http requests. All major services does same. Files are not obfuscated, do not need any extra time to decode by browser.
You already make use of minified version of jquery, and bootstrap.js. Why not minify the rest? Why not combine it to limit http requests?
This is really nonsense to stand against something that such big giants like Cloudflare or Google do from years and suggest for webmasters.
What yo can find in general Google PageSpeed Insights suggestion? Minify resources, optimize CSS delivery.
The difference is that you must do it every time when you change something in single css or js file. Then you must either change template files to use new names for your old css/js, or remember to rename and backup original files.
My script doesn't change original CSS and JS. Still you can edit it in normal way and it will be minimized/combined only once per change.
Rest do not minimize or combine anything. More than 90% of webmasters here are not that smart to find the right tools or software and use it properly.
BTW, older IE versions has limit of 278kb and 4096 css selectors. This is far more from what AVS script use for combined version of css.
Also who cares about IE 6,7,8? AVS layout already use tons of css rules that are not supported by such old browsers.
