In case anyone does not know: when a brand name becomes the generic term for a product or action, courts and trademark offices may determine the mark has become “genericized.” If that happens the owner may lose exclusive rights and the mark can enter the public domain.

See Zipper, Heroin, Escalator, Yo-Yo, etc.

So if you are anti-capitalist, you should photoshop with Gimp, google with duckduckgo and so on.
