>if we care about privacy we have to accept that people other than ourselves think the problem is big enough to warrant these measures.
Not sure what you mean here by "accept". Accept the fact those people and opinions exist? Sure! Accept their opinion without challenging, without asking questions? No.
Accept this opinion is big and rational enough for the majority to follow and make laws? No.
>You have already lost this battle
What makes you think that? That's just your opinion. You know, even when battles are lost, wars can be won later won. "Right to Repair", "Net neutrality", "Global Warming", and here: "open source hardware". All those battles have been fluid. Telling people it is over, it is too late, is a very common trick to try to influence/convince people to accept the current state. That certainly does not make it true.
I understand you may try to convince readers that it is over, because it may be your opinion. If that's the case, just be frank about it, and speak proudly for yourself of what you wish. Don't hide behind "politicians", "tech companies" and "other people".
