Like Mozilla is a "foundation" (as in board-controlled funds, there's no members) and a silicon-valley corporation in a trenchcoat.
So unsurprisingly you get: LLMs, Adtech sold as privacy-respecting, acquiring corporations and failing to open-source the technology, removing RSS/Atom feeds discovery, …

And bonus on the FOSS side of things:
- Hard-requiring Firefox extensions to be signed by Mozilla which is effectively Tivoization;
- Making DRM integrated into Firefox, which btw triggers when JS libs merely check support, instead of being an extension/plugin you explicitly have to add like for Ruffle (or Adobe Flash back then)
