My father used to repair gas pumps for a living. I went out with him on a few jobs. You'd be amazed how many large facilities that have their own fleet of cars end up setting up their own gas station. Universities, large hospitals, movie sets, and of course emergency vehicles.
Not to mention that they fully expect people to go grocery shopping every single day, or it never crosses their mind because they have no idea what it takes to feed a large family.
I had to do the grocery shopping for a household of 7 (3 of them teenagers) and the only reason I used a large vehicle to get those groceries is because there was no infrastructure for bicycles in that town. I didn't haul anything that couldn't also be hauled by a decent cargo bike.
My work uses 1 Password. It feels relatively safe. They claim that if you don't have your master key they can't restore your passwords. Can not ensure the validity of that claim.
Personally I use Bitwarden and KeePass for my passwords. They are both open source and audited by 3rd parties. I trust them.
I don't need Lemmy to be a replacement for Reddit anymore than I needed Reddit to be a replacement for Digg. It's a different platform and it's allowed to be different.
I need Lemmy to simply be a social link sharing and message board. And it's doing that perfectly.
The average user doesn't give a shit about what OS they're running. They also don't know what tools they need. I remember a client who dropped $700 on Photoshop because "How else can I resize my photos?"
Linux is to hard for someone who doesn't know why it's bad to install multiple antivirus suites. People who don't know the difference between a web browser and a search engine.
Linux will only ever be for hobbyist because they the only ones who give a damn.
I don't think there's a need. I keep my system patched and I only install from trusted sources. It might make sense in a corporate environment but for a single user machine I can't image ever needing it.
This sounds like an Ubuntu problem, sadly. Ubuntu is, in my experience, a mess of a distribution. Debian works almost flawlessly and I think you'll have less issues with a properly run distro.
I don't have hard numbers, just loose ones. From what I've read Reddit had about 400 million daily active users. From what I know only about one or two million users are on Lemmy. Now that's a massive jump from where it was just a few months ago, but it's a drop in the hat.
If my information is even remotely correct that's less than 1%.
Ublock works great on a web browser but on a Google TV/Roku it's kinda useless.
