I’ll quote my post from a different thread in case you haven’t seen it. Will add a bit more on my reasoning, though, so that it was of more value for this thread.
Also, I don’t see how anyone could be outraged having read your post, it’s perfectly valid to consider options and manage risks. I’m a “True Believer” myself and have only used Corona for any serious game projects for ~8 years, but I’m also regularly tinkering with other engines/frameworks just because I enjoy the process and prefer to be aware of how’s everything done in other tools.
To me, the most important feature currently is the support of a variety of platforms, consoles especially, with Switch being the most interesting target for me at the moment. Unity is the king of that, but as I’ve said, it’s a terribly bad tool in my book, especially for 2D (and I’m not interested in 3D at all) — why would I even go the harder route of indie gamedev if I’m just going to torture myself every day, might as well do it in some office with stable income and all the benefits. 
Corona’s already doing most other stuff I need it to, so if I switched, it’d be to something with Switch support (ha). Otherwise, it’d be easier to hire a porting company for a Corona port.
With Unity, UE4 and LÖVE out of the way for the aforementioned reasons, that leaves me with MonoGame and GMS2. Normally I would shy away from anything with an editor, but honestly, from what I saw, GMS2’s editor wasn’t too annoying, while C#'s ecosystem is just not something I like, so GMS2 probably wins by a slight margin.
As for the risks of staying with Corona, I’m just not considering it a risk at all when we’re talking about the pleasure of working with, in my opinion, the absolute best 2D engine/framework out of so many I’ve tried over the years. I don’t have 50 apps to port, and I’m perfectly fine with porting the several projects I have, especially since it wouldn’t take me long to do so.
