There is no standard what red USB A ports mean. Could be fast charging through some proprietary protocol or other special features. Or just a design choice.

USB ports with no symbol just don’t advertise what they’re capable of. Most phones support super speed data transfer. Basic USB-PD and display port output support is also common. They may also support other stuff, like pretending to be a webcam, audio output and much more. But you usually have to look in the manual or data sheet to know what is supported.

A “strawberry” is a berry only by names (it’s closest relative is the hazelnut, IIRC),

Close relatives to strawberries are other similar plants like Sibbaldia. More distantly related are roses and lots of other fruits like raspberries, apples, peaches and so on. Hazelnuts are even more distantly related (not super far, but also not super close). You’re probably thinking of hazelnuts because the small seeds on strawberries are technically nuts.

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.
