Because this makes no sense.
Do they advertise that there's no support when you pay $20? I'm gonna take a guess that they don't.
They are getting paid by their customers and if they can't sustain their business (which includes support) with it they are under pricing their product and should have consequences for it.
A business is a business and we should stop treating startups as special. They operate on the same rules and standards that everyone else does.
If this incident happened to me, I think I'd 100% give them a pass because Cursor is my favorite and most used subscription.
I've gotten a lot of value out of it over the past year, and often feel that I'm underpaying for what I'm getting.
To me, any type of business is a business. I'd treat Cursor as special because it is special.
