Had our 3rd party vendor finally check their code into our github. Great.

Checking the recent commits, they only add changed .CSS files. Hmm..odd.

We use less so why did they update the compiled CSS file...? Did they forget to checkin the Less changes...?

Nope. Backend sitecore developer updated the bundled, minified CSS files and checked those in along with the fucking node_modules folder.

Didn't even know what LESS is.

The vendors PM swears the frontend developer did the changes. I don't know what's worse.
