That calculation does not hold for developing countries. Rider's license fee is huge in countries with per capita GDP is a small fraction of USA's per capita GDP.
> Most of the people in developing countries don't need IDEs
Most people in general, I would say. I haven’t tried JetBrains editors in a while, and the “developing country” definition is very unclear in my opinion (and also part of why I roll my eyes at the “what about developing countries?” argument sometimes), but I do think the yearly price looks good for WebStorm at least, as someone living in Colombia.
For reference, at the time of writing, the standard Netflix plan costs 26,900 COP a month, which ends up being 322,800 COP yearly. Meanwhile, WebStorm’s first year comes at 298,541.10 COP post USD -> COP conversion - it isn’t an insignificant sum, but if it offers significant added value, I think it’s a fair price, certainly better than the Netflix pricing. The second year is reduced to 237,967.54 COP, and the third to 177,393.99 COP - that last one is even less than what you’d pay for the Netflix basic plan over a year (202,800 COP).
