It's my understanding that the S3 price in Turkey (£18) is approximately 1000 Lira. I read on Wikipedia the minimum wage is around 26,000 Lira per month. So this leads me to believe it is around 1 day's work to buy an S3 license.
That is for a product we have worked on for around 25 years, and you keep that license for life, with unlimited access to our services (up to the S3 license level, as long as we continue to work on LFS).
To purchase 25 years of work and unknown future years of work, for one day of your own hard earned cash, doesn't seem really unreasonable to me. I understand that in some other countries, you can work less than half a day on minimum wage to purchase an S3 license. But it's not really off the scale. We do provide services to you that cost money and huge amounts of time.
The developers don't earn that much these days, and we also need to buy food, heat our homes, etc, and spend money on servers to keep our services running.
Nearly all the other products I see on the internet, you have to pay monthly or pay for upgrades in order to keep using them. I think we have one of the best deals available for an ongoing product in continual development.
