Not all of them. I find I'm usually more extreme than others when it comes to openness and freedom. I'm usually agree with Richard Stallman. I refuse Facebook, Skype and WhatsApp because they're closed and proprietary. (How many of the anti-ExFat-folks use these services?) I'm using GNU/Linux on my PCs and phones (and I insist on calling it GNU/Linux)...

... but there's a point when you have to accept a reality outside your own little universe, even if you don't like it. Part of this reality is that people don't give a dime on what I think is correct. Part of this reality is that I've actually seen the frustration of two Jolla phone users because their SDXC-cards didn't work.

The Jolla phone as it is (and the tablet as it's planned) still lets me be as fundamentalistic as it gets in todays market. I can pay the price of letting my two friends using their ExFAT-SDXC cards if they really want to. I'm not too proud, I don't think my concerns about freedom are more important than their need to exchange data using the SD card.
