that icon closes together when you hover, and in graphic design, specifically prepress, the boundaries of the actual page are marked with this set of L shapes to indicate where to align the page cutter, which is a little bit of an abstract connection but i guess that is the intention

if you want to talk about outright symbols though... the chrome logo, the google play logo, both of these are quite well known sigils of satan - chrome logo is 666 rolled around the same circle, i'm not sure what the other one is, possibly related to the hexagram, which is also a traditional symbol of satan, you can find that somewhere... i'm not sure, maybe more related to the three intersecting triangles, since a hexagram is two, but has the same geometry, both composed of triangles, both arrayed in a different way, both having a recurrence of 6 in the geometry
