I’ve already seen number 1 happen. I’ve had a completely unacceptable amount of non-nsfw tagged porn hit my front page being posted to various Lemmy.world communities, all by shitjustworks users. I’m getting pretty close to abandoning the platform myself because I don’t need that shit coming up on my phone when I’m just trying to browse
Edit: that said, I’m not going back to Reddit. I’ll just abandon this type of site altogether and spend more meaningful time with my family and read more books
Just chiming in as a software engineer. My product DOES support Firefox, but there are some weird animation quirks that my team has been trying to solve, but with limited bandwidth and a full product backlog, it’s hard to justify spending too much time supporting a browser with such small global utilization. Especially since we’re using third party libraries like angular material, quirks on smaller browsers can be a nightmare to chase down
