I have the splash screen removed already. As you can see in my Hungry Hal game on google and iOS (https://www.scirra.com/construct2/games/hungry-hal). I am able to use a custom loading layout instead. I posted a video about it on facebook a few months ago.
IMO, the cost was very fair for not only having the splash screen removed, but that by having it removed allowed for a custom loading screen. Plus, I have the option to remove it from any of my projects from now on.
With that said, yes. I have been a supporter of Ludei for several years. There were ups and downs but it was always the best solution for my projects. I just hope official support comes back to C2.
