No, that's not what I was disagreeing with. I mean, it's not universally the case - the are all kinds of mobile phone apps developed by individuals, including on Android where the number of potential set ups between OS version and hardware is significant - and many of those truck on just fine. But that's not what I was disagreeing with.
I was disagreeing with the idea that there needs to be more support for paid mods than for donation based ones. I mean, I thought that was pretty clear from what I wrote. Of course they have different definitions, but in this case they both amount to the same thing, I think. Fundamentally, though, I don't think there needs to be many/any sweeping changes to Steam's infrastructure in order for mods to be made payable. I think it's sensible to offer a 12 hour refund or similar, in case it flat out doesn't work with your configuration. Beyond that, though, I think that if you're not convinced a modder is trustworthy, or likely to keep updating it, simply don't buy it. Again, this is the same with mobile phone apps. Some of them are donation based. Some are totally free. Some are paid. I don't think anyone would put forward the argument that smart phones would be better if there were no paid apps. Some of them have great customer service (even if it's just one person developing it), some not good. Do your research, utilise the refund, everything's OK in the world. The good mods prosper, the bad ones don't, some mods can be donation based, some will be free. Yaaaay. The power should be with the modder to set the price, and the customer to decide if it's worth it or not.
