This is my friend Ricardo. He was an enthusiastic GNU/Linux user a few years ago. He studied Oceanology and can't find a job in Mexico. To do something while unemployed, he makes web pages. He has a Mac now, and he was bitterly complaining that he can't get enough money to buy Photoshop and InDesign and some specialized tools for writers (he writes fiction, too).
I told him, “stop complaining and go back to using free software – we have the GIMP and stuff, and surely you can manage with a text editor”.
He said, “stop judging me by my choices. I would love to go back to Linux, but I don't have time to relearn everything – I have web pages to make!”.
This left a big impression on me – I was being a dick.
