As much as I like FOSS it's significantly harder to fund.
With proprietary you keep the source code, ship the app, collect data & sell it, and charge for a premium /subscription. They then use that money to fund talented devs and give them deadlines to make good software.
With FOSS it's largely contribution work by people who work on it in their free time. They use donations or paying for enterprise support, and if they do add a subscription service / premium version you can just modify the code and get it for free.
That's largely why FOSS software is behind, what's the direct incentive for someone to make it good?
