I feel like we need to talk about Lemmy's massive tankie censorship problem. A lot of popular lemmy communities are hosted on lemmy.ml. It's been well known for a while that the admins/mods of that instance have, let's say, rather extremist and onesided political views. In short, they're what's colloquially referred to as tankies. This wouldn't be much of an issue if they didn't regularly abuse their admin/mod status to censor and silence people who dissent with their political beliefs and for example, post things critical of China, Russia, the USSR, socialism, ...
As an example, there was a thread today about the anniversary of the Tiananmen Massacre. When I was reading it, there were mostly posts critical of China in the thread and some whataboutist/denialist replies critical of the USA and the west. In terms of votes, the posts critical of China were definitely getting the most support.
I posted a comment in this thread linking to "https://archive.ph/2020.07.12-074312/https://imgur.com/a/AIIbbPs" (WARNING: graphical content), which describes aspects of the atrocities that aren't widely known even in the West, and supporting evidence. My comment was promptly removed for violating the "Be nice and civil" rule. When I looked back at the thread, I noticed that all posts critical of China had been removed while the whataboutist and denialist comments were left in place.
This is what the modlog of the instance looks like:

Definitely a trend there wouldn't you say?
When I called them out on their one sided censorship, with a screenshot of the modlog above, I promptly received a community ban on all communities on lemmy.ml that I had ever participated in.
Proof:

So many of you will now probably think something like: "So what, it's the fediverse, you can use another instance."
The problem with this reasoning is that many of the popular communities are actually on lemmy.ml, and they're not so easy to replace. I mean, in terms of content and engagement lemmy is already a pretty small place as it is. So it's rather pointless sitting for example in /c/linux@some.random.other.instance.world where there's nobody to discuss anything with.
I'm not sure if there's a solution here, but I'd like to urge people to avoid lemmy.ml hosted communities in favor of communities on more reasonable instances.
Those are a different kind of pet projects, like some small random math library developed by a guy in Nebraska that a big software stack depends on (there's a relevant xkcd about it somewhere). The thing is, if support for such a project stops, the Microsofts, Googles and Firefoxes of the world are able to take over support, pay for it to be supported, or work around it in another way. Plus they are usually careful about which dependency they introduce, if something isn't governed properly or does not have wide community support... it's unlikely to be included.
Taking on a whole browser as a pet project is something entirely different. Browsers are huge and complex. You're basically betting that mr-cheffy will be able to keep up with all the changes, like security updates, feature updates and bugfixes, that upstream Firefox produces, and that he will be able to keep his own part of the codebase secure, and that he won't get burned out or bored with the project in one or two years.
For these reasons, I will never put all my eggs into the basket of some 1-man browser project, sorry.
Turning off telemetry is just a few clicks, or about:config flags in Firefox anyway. And "respect your privacy" is just meaningless buzzword bingo. If you go to facebook or google in zenbrowser, your data is harvested just like everyone else's. Privacy is a process not a product (browser).
