Unity is such a trash engine. I can understand the appeal because it is fairly easy to get started with, you can buy just about anything you need for your game(s) that you may lack the skill to provide yourself and has a huge community. But it's such a bad engine in terms of code quality and performance and it is only made worse with revelations like the above about them forcing analytics on for the free version.
It's time for more indies to start embracing any of the far superior open source engines out there. Godot and Ren'Py alone can easily be used to make any of the ero games I've seen so far. There are several other high quality options out there if you prefer working with other languages. Love is a great 2D engine that uses LuaJIT, jMonkeyEngine is a 3D engine that looks rather promising on the Java front.
The plus with all of these is that their source is available freely in case you find you need it (more common than you may think) and none of them require subscriptions or royalties payments to use. And as far as I know, none of them come with any forced analytics pushed on your users.
