People arguing to keep the ChipMixer payments at their current rates who are trying to get a bigger paycheck, they know that the campaign should decrease the rates and probably want the discussion about it to stop. It's logical, though a bit too smarmy. Contractors don't have the stability to say, "go ahead," when they could be booted from their 'job' at any time.
The member who started the whole story is not a member of the CM signature campaign at all, and all those who commented on his post did nothing wrong - maybe they should have reported off-topic or spam and ended the case?
The only one who has the right to say that the pay rate is decreasing or increasing is the owner who will pass it on to the campaign manager - I have absolutely no problem with any decision in that direction. If you and some other members think you're overpaid, request special campaign status and lower your pay rate.
Before you start with your usual philosophy, consider that I have not spent a single satoshi from the CM campaign, and that for me 1 BTC has always been 1 BTC - and I believe this is the opinion of the CM owner as well.
