While using Mathematica, you don't need to go out to fetch some random 3rd party tools, because most components are already built into it. What makes it better is that combining those components is well streamlined, and there's little need for costly plumbing.

Paywall does suck, but someone gotta curate all those shits. Mathematica is a good platform not only because of some advanced algorithms built into it, but also because of the curation from Wolfram. Curating software component is one of the least fun job in the world, and any entities who do it properly should be paid for the sake longevity of their roles.
