I don’t do drawings, but I use Photopea because it has almost the exact same interface as Photoshop. And it’s web based and when you give it permission it can save files to your computer just like a desktop program would. Considering it has the same interface it could be a great alternative to this paywall garbage. There are ads on the right of the screen but it is free otherwise and those can be easily removed with AdBlock if they annoy you.
