I have made some changes, now it has nothing to do with the previous icon file

The icons were added in

• Improved the icons of community menu with officials icon #8519

These were using a "GPL Friendly" license from Pictogrammers

It turns out that the license wasn't GPL-Friendly, specifically regarding brand icons: Templarian/MaterialDesign#5777

and brand icons were removed in V6: Templarian/MaterialDesign#6602

The logical conclusion to me would be to remove the brand icons if they're nonfree

I think this is the way to go, icons would be nice but definitely not worth the hassle.

Agreed

Remove the brand icons

@lukstbit would you like to include removal in #15190, or have someone split it out into a separate PR?

[lukstbit]

Looks good, however I think it could be better by:

• swapping the Reddit and Mailing List so all social networks links are together
• using the link icon for Reddit as well like it was used for the other social networks

Fantastic, thanks!
