As someone who was on a project that stalled for a year because our patchset wasn't accepted by a different open source project (not Linux either), I can tell you from experience that it's not as easy as folks here make it out to be. Some maintainers (and Googlers) really want you to study at their mountaintop monastery before your code is worthy, and scrutiny is even higher now due to AI, as we can see from the complaints about this bug report. Now, I've merged enough open source patches on my personal time to know that most projects aren't like that, but based on this interaction, I seriously wonder if Google's patch would've been accepted without incident.
Maybe AmaGoogSoft deserves this, but then what's the threshold? If I'm in charge of Zoom or Discord and one of my engineers finds a bug, should I let them report it and risk a public blow-up? Or does my company's revenue need to be below $1B? $100M? This just poisons the well for everyone.
