Google is not the payment processor. This is about the app including a link to a donation page on opencollective.com.

Other 501(c)(6) organizations you might have heard of include the Linux Foundation and the Rust Foundation.

Ardour does not seem to require a CLA or copyright assignment, so the maintainers don't own the copyright over contributions either way. The contributor would not be able to sue someone over a GPL violation if their contribution is public domain, but what random small contributor is going to participate in a GPL infringement suit anyway? Doesn't change the maintainer's rights to do so with any of their own human-authored contributions.

Cargo will still pick the latest for transitive dependencies that aren't explicitly specified in your Cargo.toml. This is what Cargo.lock is for.

Practically speaking, though, if a work is in the public domain, it might as well have an all-permissive non-copyleft free software license. Public domain material is compatible with the GNU GPL.

USB devices cannot directly address host memory like PCIe or FireWire, but the XHCI controller does DMA to/from host memory, and most USB device controllers have some kind of DMA between USB and the device's RAM.

No need to pretend to be HID. Windows has WinUSB for userspace USB drivers that don't need special signing.

No, serde-wasm-bindgen implements the serde Serializer interface by calling into JS to directly construct the JS objects on the JS heap without an intermediate serialization/deserialization. You pay the cost of one or more FFI calls for every object though.

You could put it under a "PostgreSQL OR Apache-2.0 at your option" dual-license, so all contributors give you their code under both licenses, instead of needing to re-license later. The Rust project does this (MIT OR Apache-2.0) to get the patents clause from Apache while retaining compatibility with MIT and GPL.

That's a bad analogy. No one is complaining about Google providing Android security updates.

This is like a car manufacturer preventing the installation of all unapproved aftermarket accessories by claiming they're protecting you from a stalker installing a tracker on your car.
