All we need right now is some heathen proclaiming he uses spaces instead of tabs and leaves braces on the same line in their code plugin, and I’ll guarantee we’ll reach Godwin’s law within 2 pages 
Jokes aside, as far as I understand the situation:
You can only request refund from marketplace in 3 situations:
Asset not compatible with current version
Bug with asset prevents you from using it as advertised
Asset info is misleading
Max and others say that people create superfluous refund requests (area below landscape empty, there should be a 0 metallic input on materials etc) for either genuine or malicious reasons to receive refund even though their case doesn’t fit the 3 situations, and thus they shouldn’t get refunds. This also creates extra workload on Epic as they have to deal with each individual refund request. Something should be done about this.
This can go two ways, and I don’t see there is a possibility of reaching an inbetween solution. Epic can crack down on superfluous refund requests and make getting refunds harder. In Max and others’ perspective this is a good thing. However, in my opinion this is pretty anti-consumer approach. Or things can stay the same, Epic can process each superfluous request case by case. In my (most likely unpopular) opinion, this is a problem that stems from lack of adequate consumer protection in marketplace.
Right now you can find countless lets play videos on almost all video games that has been released in the past 2 decades. You can see exactly whether or not a game fits your individual taste, yet STILL, Steam offers a no questions asked refund if you’ve played a game for less than 2 hours within the 7 days you bought it. You see that most developers on Steam are actually happy with this, and unhappy people are the ones that have games with questionable quality to begin with, most just treat refunds as a cost of business (like retailers do). If you look at the marketplace in contrast, most assets have very limited screenshots or videos. Even with the most meticulously described asset, you still don’t really know what you are actually going to get. Yet only refund options are technical situations, there is no care for customer satisfaction. No wonder why people claim superfluous refund requests to be honest, they have no recourse if they are deeply unsatisfied with the asset they bought.
Again, in my most likely unpopular opinion, Epic should allow no questions asked refund requests, provided the asset in question is still in the refund period (1-2 days, 1-2 hours after download, or something else, you choose), and their account is in good standing (no serial refunds). This removes a lot of the risk from the consumer, they can more freely buy an asset, and return it if they are unhappy (which, honestly, they should be able to). No more expensive individual support requests for Epic to process, refunds get normalized as cost of business within marketplace, and free market sorts out the rest.
Some vendors point out the piracy element in this. Concern is people would just buy and return while keeping the assets. Well, they can do that now with piracy if that was what they were after. This isn’t an with Steam, even with DRM free games. On the games that do have DRM, circumventing it is as easy as copying a modified .exe found from simple google search. All in all, people would do such a thing, most likely wouldn’t bother with providing payment info, getting billed on their credit card with however minute interest, consider constantly changing exchange rates, and getting back the money after up to a month later (In one case I ended up waiting 2 months for a refund from an online retailer). While that is what first comes to mind, I don’t think it’s a likely scenario that would happen as often as people make it out to be (and I don’t think that is what is happening now). Worst offenders could get banned (if they aren’t using stolen credit cards to begin with), and Epic can place a refund cooldown period, say, 7 days of no refund afterwards for example.
At the end of the day, this comes down to whether or not you want to keep the money of the people that are not satisfied with the product they received, and whether or not you treat every customer as if they are a pirate and liability.
