I'm sorry, but I do not fully understand your comment. "It could disappear tomorrow" ? Sold has written on their blog that they are shutting down their company..
Also, it's not like if Microsoft was shutting down. You'll be deprived of a couple of products, at most.
I wonder if startups are starting to see a reluctance in users to fully buy in to trying new products. This reminds me of one S13 YC startup that got bought by Pinterest a few weeks ago..
