How does this work? Normally I download and install TTF files and install them on my computer. How are licensed fonts work? Is there some kind of proprietary installation?
For example, if you visit my webpage, your computer will download the copyrighted text from it and save it in your cache.
If you (the website operator) link to a font from your CSS file so end users' browsers will download and render text with it, then you (the website operator) are paying the licensing fees.
