Advertising things that arent a direct conflict of interest just results in poorly targeted ads, which both consumers and advertisers don't like.
On the "open source" side, its not enough that the firmware is open source, the flashed binary needs to actually be unmodified. Marlin and klipper run 99% of the budget 3d printer space, and both are open source projects. There are still dozens of printers that are shipped with modified firmware with the changes kept secret. GPL is only as powerful as your lawyers are.
Is there a way to figure out if a product is shipped 100% open source? Maybe a website that keeps track of how open/closed each company is? Otherwise do you know of a way to reflash the system with an open source project? Something like a new OS from github? I've found in any hobby there tends to be a brand that has gotten lots of mod support from the community
Other than building the firmware and flashing it yourself not really?
Usually they will have flashing instructions somewhere, and thats a goodish sign. Even better if they have the source code published somewhere. But unless you build it and flash it yourself its impossible to know what is on there.
For a real-world example, many Anet A8 machines were shipping with "marlin", but with the runaway thermal protection disabled.
