@LorenzoAncora I don't believe the virustotal scanner is setup to scan malicious JavaScript and assuming it does, of course it would whitelist all of google's JavaScript.

That virustotal page of course loads obfuscated proprietary malware from google; https://www.recaptcha.net/recaptcha/enterprise.js thus it cannot be trusted to confirm that files aren't malware (although it might still have some use confirming that certain files are malware).

>you've linked to are minified (compressed), not obfuscated.
The tag manager script I've linked to is both obfuscated and minified, although minification alone is often quite effective obfuscation.

If the source code is also provided and that exactly corresponds with the minified version, the file isn't obfuscated, otherwise it is.

>Almost all websites use compression to improve loading times.
Yes, many websites use GNU zip (gzip) compression on served files to improve loading times.

Minification doesn't improve loading times unless you want to load 12MiB+ worth of JavaScript.

>You can simply use the auto-format of your text editor to read minified scripts with minimal effort.
Auto-formatting won't restore meaningful function names and comments.
