It is no coincidence big tech rejects, in unison, bitcoin.

Big tech is tightly wound with government and benefits from the arrangement.

Bitcoin removes some of the power that the government wields and over time forces governments to change.

By declining to support bitcoin and working against it in various ways, big tech is essentially extending the amount of time where they benefit from their ties with the government. Only when big tech is forced to change towards adopting bitcoin (i.e., or else they lose market share) will they begin to acquire bitcoin on their balance sheet and integrate bitcoin into their products (e.g., accepting bitcoin as payment, designing products to take advantage of bitcoin's properties, like how maybe Reddit could become more like SN if they wanted to.).
