You apparently have no idea how game design works.
RadicalGames, you need to calm down and stop insulting everyone who doesn't agree with you. I am prepared to give you the benefit of the doubt, but you need to work with us here. Lets break it down shall we.
You have made multiple claims, and accusations.
I got scammed into buying a licensed version because they claimed it had working exporters for lots of platforms. Complete lie and the exporters don't work properly and many don't work at all.
What proof do you have that the exporters dont work at all? Did you personally encounter bugs in export of the application? If so did you make bug reports on the Scrirra forums you can link?
After a quick google search I could not find any exporter threads on their forums older than 2014.
The engine is full of bugs and Scirra owner Ashley will not do anything to fix them and after 5 years there are still hundreds of bugs in the engine causing games to crash or not export right and all kinds of editor glitches.
All software has bug, all software has a bug fix backlog and some bugs that will simply never be fixed. What bugs did you encounter in the engine? did you make bug reports on the Scrirra forums you can link? Can you link a bug thats been open a long time that they have refused to fix?
Now they are trying to scam people in to getting a subscription engine where you have to pay $99 up front and $99 a year but you don't own anything and you can't edit your own games without the subscription. If they go out of business (very likely) or just stop renewing your subscription you are totally screwed and you can't even open your own games.
This is interesting, I would very much like to know if this is true. If it is true, it is not illegal. When you buy any software, there are terms and conditions you have to agree to, if in the terms it says that they can refuse you access to anything you upload to their site, then people need to be aware of this when they get the subscription. However it seems highly unlikely to me that they would lock me out of my own games if I cancelled my subscription. that would not be good for business, it seems far more likely that they would simply remove a load of features from my account, such as the ability to export my games to a certain format. Which is perfectly acceptable. If you cancel your netflicks subscription do you still expect to enjoy netflicks services for free? thats not how the world works.
I just checked on their FAQ page, here is an exert that completely counters your above claim that they will lock you out. As I thought, they will restrict your export, but you will still have access you all of your assets. I see no problem with that.
"What happens when my subscription ends?
You'll still be able to open your projects in the free edition, but you will not be able to edit or export them. You will still have access to all your files and assets."
"Can I continue to sell my games after my subscription expires?
Yes.
You do not need an active subscription to sell your games once you've published them."

The new C3 engine is a total joke and crashed even on their own demo games. 12 pages of bugs in the first day and hundreds of bad reviews of it in the forum that they are now banning members for and hiding.
Its beta software, there will be bugs, and they are a small company, they cannot fix hundreds of bugs in a few days, it will take time. Based on the threads you linked, they are active on the bug fixing already.
Now they are claiming they will build new runtimes for the engine which is what we all thought they were doing to start but is really an excuse for creating a disaster of an engine and they want people to subscribe without seeing any of the features and exporters working because they don't even have them coded yet.
Bold claim, links to evidence of this?
Personally, I have used C2, and taught a game development course for kids where we made several projects and all of the exports worked fine. Perhaps you have simply not implemented your game correctly resulting in a buggy export?
Have a pleasant day :D
