I don't think it's all that unique to the Gopher fan base. Many other college athletic programs, even in other sports, have fan bases that get quite upset in regard to certain media outlets. This is even true for blue bloods and national powerhouses that have consistent success.
What I think the issue is in the Twin Cities and Minnesota in general, is that for the past several decades the Gophers have often been behind the four pro teams in terms of coverage. So, when media members, whether it's in print or broadcast, give the Gophers a hard time, I think there's a mentality where they're sort of "piling it on." What I'm getting is that there's a sense that the media largely ignores the Gophers, and when they do pay attention, it's usually in a negative light.
In all fairness, it's not surprising that the press is focusing on negative takes right now as a result of the football team's record. However, one of the things sections of the fanbase have trouble with are how it's presented. Often times it's done with a lot of snark and jabs at the program, rather than being a more straightforward, nuanced approach that focuses on the numbers and statistics from game-to-game.
For me, it's one of the reasons I've grown more accustomed to reading the takes from SB Nation.
