True, tho that's only one of many ways to get locked-in. Just to name three: 1. what if I want to switch platforms? 2. what if they switch business models? 3

True, tho that's only one of many ways to get locked-in. Just to name three: 1. what if I want to switch platforms? 2. what if they switch business models? 3. what if they go away? The only real concern is #1 with Sketch, and that's your (org's) choice so you do have some choice in the matter. Since the format is well-documented there's ways to move away if #2 and you still have access to existing software with #3 (save issues with a licensing server perhaps). Figma is a concern with all three unfortunately. Everything I see about its capabilities is amazing, but I've resisted for this reason. Hopefully they open their format.
