I think the main pro of this system would be that it requires no trust. The immutability would be actually a con for privacy: if you’re burned or doxxed later, there would be hard evidence of your identity in the blockchain.
Besides, solar photocells have a limited lifetime. Recycling them is possible but expensive so people just make new ones instead. Kind of like plastics if you think about it.
My opinion is that what matters is how much money each part of the network receives.
For example, instances tend to be transparent about their funding. And we can see that some of them are just months away of being out of cash. Meanwhile, we see people subscribing(!) to a very expensive app that charges $20 to remove ads (and tracking and data collecting) otherwise.
I think is okay to keep people aware of these things. Getting defensive about it is just a waste of energy. For both sides.
Look, if people come to you in good faith to learn and you reply like this, how are you expecting to organize and positively influence people around you? Are you gonna build socialist utopia alone?
The idea is to build stuff together right? If you’re antagonizing everyone, how do you expect to achieve that?
