I'm not worried that I'm going to lose access to V2. I'm worried that they are moving in the same rent-seeking direction that Adobe did that caused me to migrate to Affinity in the first place.

Creative tools are, to artists, like IDEs and git repositories are to coders.

Imagine you spend years getting very proficient at specific development tools, and you use a repo host like GitHub. One day your dev tools providers tell you that they are moving to a subscription model. You can continue to use the legacy stuff to access your source code. But if you choose to migrate to a new vendor, all of that legacy source code is now coupled to your old dev tools. Hopefully you have some sort of export -> import functionality so you can migrate. But this doesn't help the fact that you spent years honing your craft in a particular eco-system and now that ecosystem has deal breakers AND make it cumbersome and difficult to migrate away.

An artist has "source" files just the same as developers. They are the project files that have all of the raw layers and assets that would allow tweaks and revisions to be made.

For some artists, this can even make contracts difficult. I own a business, outsourced the creation of our logo to a local artist. Years down the road, if I wanted to ask her to send me the file in a different format, or make tweaks etc. she may charge me money for that, but it is totally on the table.

Imagine one day that happens and she has to tell me "Sorry, due to vendor lock-in and bullshit I had to switch to a different program and no longer have access to all of the project files that went into creating your logo."
