I feel like everyone is very negative about something that hasn't happened yet. This gives a desktop environment to Canva users, where the revenue actually is. It's both a trojan horse and a usable product. Will everyone's worse fears come true? Maybe, maybe not. Mean time you have an excellent app, for free, and very few software products, free, open source, closed source, perpetual, subscription.... last "forever". They are often obsoleted by some new product, new workflow or just a new OS. Take it for what it is right now.
Bit late to this thread, but you mention their design defects which bother the shit out of me. It’s been this way a long time now, but I hate, absolutely HATE how they changed save as (cmd+shift+s) to duplicate document in some of their apps. And then you close the duplicated document because that is not what you wanted, and it asks you if you really want to delete it. Delete what? It does not exist on the file system! I know one might say that technically it does or something because of versioning or some shit… the way every other OS and non-Apple app works was not broken. And I dont know anyone who likes pasting in text formatting as a default. MS broke that too. Why would ya change the functionality of an existing keyboard shortcut?
