Answered from the vendors’ own pages

MUI: Is MUI free?

The core library is open source and free. Advanced components, including the full-featured data grid, require a paid licence.

pnpm: Is pnpm free and open source?

Yes. pnpm is free and open source software developed for Node.js. Version 10 and 11 are currently available.

Source
MUI: Can MUI look non-Material?

Yes, through the theming system, but a substantial departure takes real work. Teams wanting full design control often prefer unstyled primitives instead.

pnpm: How does pnpm save disk space?

pnpm uses a content-addressable store with hard linking and symlinks to avoid duplication. All files are saved in a single place on disk and hard-linked to individual projects, dramatically reducing storage requirements compared to npm.

Source
MUI: Does MUI handle accessibility?

Components follow WAI-ARIA patterns by default, which is a large part of why teams adopt it.

pnpm: Is pnpm faster than npm?

Yes. pnpm performs installation in three stages: dependency resolution, directory structure calculation, and linking. Packages are fetched and linked as soon as possible, making it significantly faster than npm's sequential approach.

Source
pnpm: Does pnpm support monorepos?

Yes. pnpm has built-in support for monorepositories. You can create a workspace using pnpm-workspace.yaml to unite multiple projects in a single repository.

Source
pnpm: How does pnpm handle node_modules differently than npm?

pnpm uses symlinks to add only direct dependencies to node_modules root, preventing accidental access to undeclared dependencies. This encourages more explicit dependency management compared to npm's flattened node_modules structure.
