I want the people who make Firefox to make decisions about Firefox based on what users have been asking for instead of based on what a CEO of a for-profit decides is still not going to make them any money, just like every other plan that got pitched in the last 10 years that failed to turn their losing streak around.

It's not a knee-jerk reaction to "AI", it's a perfectly reasonable reaction to Mozilla yet again saying they're going to do something that the user base doesn't work, won't regain them marketshare, and that's going to take tens of thousands of dev hours away from working on all the things that would make Firefox a better browser, rather than a marginally less nonprofitable product.
