Bitpay has proved many times that they are anti-Bitcoin. Everyone can greatly contribute to Bitcoin just by not using Bitpay.

If you're a merchant, then switch to BTCPay Server. When using Bitpay you share with them not only a slice of payments, but also data about transactions and customers. This data then sold/shared with chainalysis (serving government agencies) and probably others. Also both you and your customers become guinea pigs for their various anti-Bitcoin experiments, such as an attempt to force everyone to use their BIP70 payment protocol.

As a buyer, switch to vendors accepting Bitcoin without Bitpay. When buying something from a merchant you tell other players on the market that you're ok about HOW that merchant does the business. And if there is some issue left without your reaction, it becomes a widespread norm. Buyers are the crucial link in the chain. If a direct Bitcoin payment will be a requirement to get your bitcoins, then merchants will have to either provide that or be replaced by others and leave the market.
