Major parts of today's internet are controlled by extremely powerful corporations - that's just a fact. Private individuals and even committed activists have very little to no influence on how these corporations shape their part of the internet. Hence the analogy with climate change: this problem, which threatens the whole of humanity, could probably also be solved, or at least be tackled in a meaningful way. However, a solution is only possible if those corporations that are largely responsible live up to their responsibilities. Of course, this is not to say that private individuals should give up all hope and not try everything they can. Look at it this way: every post or comment on Lemmy is the equivalent of a properly disposed plastic bottle - just a drop in the ocean, but a drop nonetheless. What I was getting at overall is that you can certainly make a contribution, but this small contribution will be of little use as long as those who are actually responsible do not live up to their responsibility, because only these players could turn the tide for the better; but unfortunately they don't; quite the opposite, I think. Nevertheless, every contribution to improving the situation is important. So please don't let my pessimism get you down.
