European Solar Manufacturing Organization Warns of Cybersecurity Risks in Europe’s Solar Infrastructure Due to Chinese Inverters

(Or perhaps if things need to connect to some kind of grid management services, a firewall with appropriate rules — i.e. ones that do not allow connections to or from random addresses in China. Or some combination of both. Depends on the requirements but it's not that complicated. Consult your local IT security expert.)

No, not that, i'm talking about reverse-engineering the inverter's firmware to code a new, alternative one with guarantee of no backdoors.

Exactly. But some EU politicians apparently have trumps micropenis stuck up their ass so far that it seems to interfere with their logical thinking.

there's no credible threat of US invasion

Let's just ignore the threats of taking Greenland, Canada and Panama... and whoever else will get added to that list.
\ I mean, it's not like the US has invaded a bunch of other countries in the past decades, right?

But accusing others of being a tankie. Quite ironic.

The only whataboutism is coming from your comment.

1. I was not saying that we should just let China do its thing. I was saying that instead of just focusing on China, we should be banning the companies which have are by law obligated to provide backdoors too.
2. the US is a fashist state, and if you somehow really think its not threat enough that trump is arresting children and sentencing them without lawyers, as well as sending immigrants to KZs, you should really see a doctor.
