[edit] in summary, in the age of open access, FLOSS science tools become a must -- and a collective responsibility.
If those tools make it impossible to share data, or publish results reproducibly, then I'd agree that those tools suck. However Matlab reads and writes every damn format under the sun.
Don't confuse "create, invent and build" with "export and publish." They're fundamentally different tasks.
Yup, startups have costs. Go figure. And sometimes you get what you pay for.
I wish I'd learned Matlab sooner. I still love the Python ecosystem, but Matlab's replaced a LOT of dicking around in Python for me. It does completely different things, and certain things are trivial or impossible in each place. Worth learning both.
