There is a lot about Bending Spoons in this community. A very recent discussion:
Should you move somewhere else or not? I don’t know, but “free” is not something that comes to my mind when thinking about Bending Spoons. Then again: there is no such thing as being “free” and sustainable in the long run (if not FOSS or small indie tools running on your own hardware), especially not with services that run on servers in a datacenter connected to the internet. Somebody has to pay. And I think Bending Spoons is aware of that. They know how to make people pay for sure. More on the topic in the thread I linked to above.
