I am a MATLAB and Python user who has flirted with julia as a replacement. I don't love the business model of JuliaHub, which feels very similar to Mathworks in that all the cool toolboxes are gated behind a 'contact sales' or high priced license. The free 20 hours of cloud usage is a non-starter. Also it seems that by default, all JuliaHub usage is default cloud-based? on-prem and airgapped (something I need) is implied to be $$$.
Open sourcing and maintaining some components of things like JuliaSim or JuliaSim Control might expand adoption of Julia for people like me. I will never be able to convince my company to pay for JuliaHub if their pricing is similar to Mathworks.
I don't think this is really a good comparison. Matlab is a $150 for a personal license for the language itself ($1000/year for commercial), and if you want any packages, all the packages are extra on top of that. Julia is fully open source, and has a strong open source package ecosystem (I think we're up to 10k packages by now). Juliahub provides some enterprise systems like JuliaSim, but the language itself is totally free.
