I guess the question that a person at Google who discovers a bug they don’t personally have time to fix is, should they report the bug at all? They don’t necessarily know if someone else will be able to pick it up. So the current “always report” rule makes sense since you don’t have to figure out if someone can fix it.
The same question applies if they have time to fix it in six months, since that presumably still gives attackers a large window of time.
In this case the bug was so obscure it’s kind of silly.
It’s possible that this is a more efficient use of their time when it comes to open source security as a whole, most projects do not have a problem with reports like this.
If not pumping out patches allows them to get more security issues fixed, that’s fine!
From the perspective of Google maybe, but from the perspective of open source projects, how much does this drain them?
Making open source code more secure and at the same time less prevalent seems like a net loss for society. And if those researchers could spare some time to write patches for open source projects, that might benefit society more than dropping disclosure deadlines on volunteers.
