Honestly I don't care if service I am using converts bitcoin to FIAT or not. The one thing I care for is direct bitcoin acceptance if that requirements is met then I am fine.
I hate the idea of imposing on merchants any rules, they can do whatever they want with their money: convert, invest or hold.
Exactly and this type of attitude towards businesses who convert bitcoins to fiat will only push people away, let the business owners decide how they want to run their business, not everyone understand or is familiar with safe keeping and/or using bitcoins, which is why they use services like Bitpay which does the job for them. If Amazon decides to accept Bitcoin tomorrow by using a similar service like Bitpay, would you expect people to not use Amazon?
People who use bitcoin as remittance services, also converts them to fiat, even miners sell bitcoins to cover for their expenses, it's a currency, everyone is free to sell/buy it, more businesses accepting it, increases the trade and it ultimately helps bitcoin become more popular.
