I remember some years ago there was a "malware" going around that would flash OpenWRT onto people's routers, and set them to have more secure default settings.
There should be another thing like that, but one that upgrades Windows into a Linux distro.
Retro Handhelds are helping to bring it back.
Lookup veganic farming, and veganic permaculture. The idea that animal ag has any place in combating global warming is demonstrably false, and was nothing more than a greenwashed hijacking of the other various regenerative agricultural movements. There is no room in neither a just world, or a sustainable one, for the exploitation and consumption of animals.
As an avid bicyclist who tried their best to live car-free: it's easier said than done for anyone living in the US. I used to make 7 mile commutes to work, even in winters that could go below zero some days. It's doable, but it wasn't easy either. I completely sympathize with anyone who wouldn't want to bike in those conditions, even if a whole bunch of people do so in places like Finland.
But the worst part is the infrastructure. Motor vehicles dominate everywhere. Motorists are routinely hostile to bicyclists. Despite my best efforts to be safe, I've had multiple close calls and was once nearly rear-ended by someone who was going about 50 mph. Technically I did get hit - I had veered to the right just in time to feel the side of their car brush on the side of me. Miraculously suffered no injury, and only one of the support bars on the rear rack had been dented in.
Point is, unless the infrastructure changes, I would never expect others to switch to biking. It is dangerous.
A real keyboard and general tactile-oriented inputs. Touchscreens are okay as a supplement like in the DS or Samsung devices that have a pen, but touch-centered everything has never stopped being a frustrating user experience. Even worse is the way companies have embraced it for business use as well. Heavy industrial machinery should not come equipped with unintuitive little interfaces that are clearly an afterthought at best.
The other thing is the general desktop metaphors, and file/folder structure. The way that Android, and so many apps, hide the file system from the end user just leads to more confusion when the user needs to use a file manager to track down where those apps have actually stored data only to (maybe) find them in the most pointlessly obscure locations.
An open-source, federated, and privacy-protecting alternative to the dominant advertising services. Something that gives the individual web user full control of which ads they see; from which indies, organizations, companies or any other groups. And where they can also filter ads based on clear categories, values, or tags, rather than everything being dictated by algorithms and "relevancy".
Science is not atheism.
Another unpopular opinion: despite being popular, religious bigotry is still bigotry.
I'm a little surprised by how much incredulity there is in the comments here. It's amazing that anyone, let alone so many people right now, would think that taking away all the most protective foods (ie., plants in their whole, intact forms, which are almost invariably high carb), and in most cases replacing them with the very substances most strongly associated with our number one killers, cardiovascular disease and cancers, (ie., animal flesh, dairy, and insane amounts of saturated fats), and act surprised when it kills them faster.
Windows never breaks? Uhhhhh, that's definitely not true. When I have to use Windows, I brace myself every time I have to update.
