Well, they didn't necessarily give in to solipsism. The original idea was meant to accommodate, I think, the idea that different subjects could have entirely different experiences and still share a world. Actually, I think Husserl's idea that lived worlds have 'horizons' (beyond which you can somehow anticipate something you don't see) can capture the thought that the experience of others can be somehow be part of our own, so solipsism is partially defeated. But this is just a rough thought.
