VB6's strength was that Windows was a virtual monopoly at the time. Today you have more fragmentation, where the user masses are still mostly on Windows but the developers are mostly on Macs or Linux. Developing a desktop GUI framework for a single platform is relatively easy. Developing a cross-platform GUI framework for three or more platforms is extremely hard. And a lot of people would STILL ignore it if it's not "mobile first", targeting iOS and Android too (meaning that it's probably dogshit for desktop apps).
