You can’t hide behind a bad analogy simply due to it being an analogy. It’s still bad. McDonald’s doesn’t get paid until someone buys a burger. Walmart doesn’t get paid until a customer leaves the checkout. This is very normal for businesses that you don’t get money until the consumer buys your product. If I start an independent business selling socks I can make all the socks I want, I don’t get paid unless people buy them. That’s a normal risk to starting your own business.
All of this is besides the fact that I don’t blame devs for taking the offer, I blame Epic. If a game later becomes available on another service I will consider it then, I will not let Epic have any of my money.
You’re also completely forgetting about indie devs.
Okay, let’s ask an indie dev.
Does McDonald’s wait 2 or 3 years to get money for the work accomplished to make that burger?
To make that burger they need to acquire the property, get permits, build the restaurant, purchase and receive equipment, get more permits, train staff, get supplies, advertise…
Yes, all that will take 2-3 years. I worked at a McDonald’s that was getting rebuilt and the process for a restaurant that already existed took longer than 2 years.
Thank you for focusing on the last relevant part of my comment to signal that you don’t have any actual valid criticisms of what I said.
