I don’t understand how they are supposed to “sell your data” if you just never use a Mozilla account and uncheck all the telemetry. Its not like they can secretly steal your data, since its Open Source.
It seems to me like just more FUD that Google is spreading to undermine our trust in free software.
How can Firefox not be open source if its sources are under the MPL2 ?
It has always been the case that Firefox is a trademark and you can’t distribute it under that name. However if the code is open source the project is too.
As of today, the latest Firefox Version 135.0.1 Binaries are released under MPL 2, which is open source.
Whenever the terms are implemented, the Terms of Use will replace the MPL for the binaries. Open source has a strict definition and goes beyond source code.
The Terms of Use, as current proposed, would violate #5 (“No discrimination against Persons or Groups”) as the TOU allows for Mozilla to terminate your use of Firefox for any reason.
As a result, their binary moves from Open Source via the MPL to Source Available, via a proprietary license.
