I think especially since the UI overhaul in Blender 2.8 the project has been on a steep upwards trajectory. The software was always amazing, especially since it was free and open source, but the new UI and all subsequent improvements really put Blender on the map as a serious tool and not just an alternative for when you don't have money for the big players.
It's a self-reinforcing loop. Once a FLOSS tool becomes good enough , it'll start to attract professional users, who are willing to invest in it, which makes it even better. And it is quite hard for commercial players to compete with free. But FLOSS software is mainly made by developers. Who like writing new flashy features, but are awful at UX, and making sure all the small kinks are worked out. So most FLOSS softwa…
It’s kind of the open source counterpart of how in proprietary software, some types of bugs tend to get perpetually kicked down the road to make room for development of features that are perceived to be of higher likelihood of increasing revenue.
In theory, FOSS projects have more agency to correct this class of problem than their proprietary analogues do because they’re not subject to the same economic pressures. This however requires leadership with a strong vision for the project and soft skills to unify and motivate contributors to work on not-so-sexy bits, and this type of individual is rare in that space.
