Adams has become a controversial figure in recent years. Regardless of what you think of him, as someone who has worked in Corporate America for over a decade, there really isn't anything quite like Dilbert to describe the sort of white collar insanity I've had to learn to take in stride. My first workplace as a junior developer was straight out of Dilbert and Office Space. I have a gigantic collection of digitized Dilbert strips that best describe office situations I've run into in real life – many of them including the pointy haired boss.
He's expressed a lot of what I would consider... stupid opinions these days, but I would be sad to learn he's no longer with us.
Adams, himself? Not so much. I think he tends to have a rather nasty outlook on humanity, and I had a hard time reconciling it.
I do know that he was/is pretty much about as far away from Diamond Joe* as you can get. Interesting that they seem to be fighting the same battle.
Don't stream it and don't buy a new copy unless someone completely unrelated owns it now, but you can still listen to, watch, or read the stuff you loved before you knew what was going. Whatever you already owned didn't suddenly become toxic. Used book/music/movie stores exist. Piracy is always an option.
That's not to say a few people haven't managed to ruin it beyond my ability to enjoy their content no matter how much I used to love them, but there's no reason to give up something you enjoy just because you learn the person or a key person behind it sucks.
