Who pays first? The user, the content creator, or the content host?
I couldn't care less. If my adblocker is that final straw that caused a company to go out of business, brings on the collapse of the internet as a whole, and ultimately the breakdown of western civilization, then all of it deserves to die. With that knowledge, I'd still update by block lists and donate to adblocking projects.
I've administered BSD servers professionally and I have to say that it was one of the nicest, most consistent, operating systems I've worked with. I've worked with Linux since the mid-90s and done more than my fair share of Windows Server/AD admin. and I would gladly manage a room full of BSD hosts again.
