Why do some audiophiles beat up McIntosh?

I've been around audio my entire life. I'm 45 and I bought a decent Technics system when I was 12 with my paper route money. Genesis speakers built in New England which were actually pretty darned good. I would spin vinyl every single day to the point it drive my parents crazy. My buddies father had a McIntosh system that I was in love with and he was allowed to play it. It was haunting for me to hear his fathers system.

Fast forward 28 years later and I'm perplexed at the hatred I see posted online about McIntosh. Is it really that bad or is everyone upset that McIntosh is so successful? It doesn't make sense to me that the resale value is the best in the business yet audiophiles bash them. I personally have always loved their gear and sound. I don't own any, and probably never will. Still, I just don't get it. I've always admired McIntosh. Looks aside, I always enjoyed the music. Can someone tell me that they're junk or do you just not like the presentation?
