When measuring lengths and time, metric units are super useful. Micrometers, Millimeters, Centimeters, Meters and Kilometres are easily and often converted in a lot of technical jobs.
Same with nanoseconds, milliseconds and seconds when dealing with time in simulations or other computer programs (e.g. game development).
Milliliters, Centiliters and Liters are commonly used in cooking.
What’s wrong with hectometers? I don’t know how often they’re used but dealing with a factor of 10 or 100 to the next “regular” unit (meters or kilometers) is no big deal.
The basic software like the Intellij Community Edition is also fully open source. (And it’s not actually basic at all. It’s a great full featured IDE)
Basically you’re only paying for their support/updates and for specific language and toolkit support, which makes sense to me. They need to pay their staff somehow.
It’s not comparable to Adobe or other crappy manufacturers where you own nothing.
