It's not open source, but the Trezor firmware remains open source, unlike Ledger. Trezor picked this one because no NDA is required, so bugs can be reported transparently.

Chips are hard, technically the other chips that Trezor has had since day 1 are not open source either. But the code that runs on them is.
