A fine example of tactical decolonialism implemented in software:

Pikari Mai! is a browser plugin that replaces news and gossip about the UK royals with indigenous news. It was written by Māori artist Hāmiora Bailey to "switch off the toff", quoted (Guardian) as saying:

“People are sick of it – they don’t care about how much a diamond costs and who’s wearing what dress [...] “Across the globe, Indigenous folk are tired of [this] rhetoric around frivolity and class.”
