It only helps regular people as long as nothing breaks.
You’re still beholden to the huge company that’s making the panels, or the company that’s installing and maintaining them. On property panels are only as decentralized as your personal ability to install maintain and repair them. Off property panels are only as decentralized as the conglomerations that own every solar farm and wind farm.
You aren’t “getting away from huge companies.” You’re just increasing the minimum footprint and ecological disruption needed to generate the power needed for modern life. Let alone the amount of increase needed if EVs are ever going to have a chance at challenging ICE for majority market share.
Even assuming they’re mostly spam, you still need to listen to them in order to sort out which messages are legitimate.
I understand being annoyed by the task, but this is a job that’s justifiable. It’s not some petty make work bullshit (unless these messages have been collecting for months, then they can probably be safely ignored). Either way, it doesn’t seem worthwhile to try and get all petty revenge about the situation.
