The issue here will be securing a conviction or affecting actual change. I suspect the cost to conviction/prosecution (for the Uk taxpayer) will be so high, and the fines/action so small for the respective platforms, it will hardly be worth the effort. Most likely companies will be fined retrospectively for a bit of government PR.
