Are all included fonts free to use commercially?

Hi, I would like to use the Helvetica fonts (Adobe X11) included in this repository for a product that will be sold commercially, but I can't tell if I am allowed to use that font without paying for a license. From a quick google search it seems that you need to buy a license to use Helvetica, but does that apply to this distribution? I would appreciate any insight.

There should be a copyright notice for every font in u8g2. This is the one for the Adobe X11 fonts: https://github.com/olikraus/u8g2/wiki/fntgrpadobex11#copyright

The original copyright notice should be here: https://gitlab.freedesktop.org/xorg/font/adobe-100dpi/-/blob/master/COPYING?ref_type=heads
