There are a number of reasons for this. 1. They are not biblical in their operation. Salaries, Sunday services, buildings or much of any of it is in the Bible. 2. They don't preach the Gospel anymore. It's a watered down version. 3. They are more like clubs than anything else. The people are haughty and rude. 4. It's all about money collection and butts in the seats and little else. It's obvious. The reformation didn"t go nearly far enough and it's morphed into something The Lord doesn't even recognize.
