Maybe I'd care more about the language if this was just some random blog... But these guys are a bit different. There's always some data and process explanation behind each of their posts. They might not be great programmers and OS contributors, but they're doing something really important anyway and are doing it in a pretty transparent way. There were many situations where I learned something from Phoronix or found a performance-related answer there. They're also a bit different from other blogs in that they follow up on a story. While others report "this is broken, whaaa!" and find a new topic the next day, Phoronix will write up posts about ongoing progress to fix the thing (typically).

For the effort they put into it, I can completely ignore the language they're using. And if they blame a specific thing/group... as long as they're correct - I don't mind :)
