Twitter was quite diverse actually (it might still be, I can’t say). You had the far left, far right, and everything in between on there but it worked somewhat because the algorithm kept people mostly in their bubbles unless they went seeking it out.
And businesses would stop burning fossil fuels if renewables had the same portability, same output, were cheaper, available everywhere, and didn’t require learning a new skill set. They can still be criticised for doing so, I’m not sure what your point here is?
