In addition to which - they were never that solid in the first place. They (and Facebook) are mostly just "dumb hosting" for other people's content - if the content producers leave, they don't have anything to offer. They don't even really own the content that was produced on their platform and it wouldn't have any value even if they did. There's a weak value proposition there: "we'll let you put your stuff up for people to see and even sort of promote it, but we'll run ads next to it to offset our hosting costs", but neither seemed to realize just how precarious their position is/was.
