This isn't something new. This is how society has functioned throughout history. Democracy is an ideal, but no country is truly democratic. Show me a country where the parliament or whatever legislative and executive bodies they have is truly made up of common people voted by their peers, and not part of the upper class.
Let's be real, they did it because they didn't want people training AI models without paying them. They didn't give a shit about 3rd party apps.
Fuck up #1: no backups
Fuck up #2: using SD cards for data storage. SD cards and USB drives are ephemeral storage devices, not to be relied on. Most of the time they use file systems like FAT32 which are far less safe than NTFS or ext4. Use reliable storage media, like hard drives.
Fuck up #3: no backups.
The honestly prefer the bottom one than the modern 50 step wizards that take 10 seconds for each page to load, and load an ungodly amount of JS scripts.
A company I worked for was using an ancient bug tracking tool (called Pivotal) that looked like a 90s site. It was so fast and responsive. Later, we moved to something modern. It was 10 times worse, significantly slower and overly complex.
Another reason why copyright should be shortened... Society has changed massively in the last 100 years, but every expression of our modern society is locked behind copyright.
Because your rights have been eroded by decades of deregulation and lobbying. And because publicly traded companies are legally required to maximize profits at all costs.
What are you going to use it for? You have to give us more details, a vague question will lead to generic answers that will probably not be the best choice for you.
A dishwasher... For a family, it saves a huge amount of time and water.
Self hosting basically means you are running the server application yourself. It doesn't matter if it's at home, on a cloud service or anywhere else.
I wouldn't recommend hosting a social network like lemmy, because you would be legally responsible for all the content served from your servers. That means a lot of moderation work. Also, these types of applications are very demanding in terms of data storage, you end up with an ever growing dataset of posts, pictures etc.
But self hosting is very interesting and empowering. There are a lot of applications you can self host, from media servers (Plex, Jellyfin), personal cloud (like Google Drive) with NextCloud, blocking ads with pihole, sync servers for various apps like Obsidian, password manager BitWarden etc. You can even make your own website by coding it, or using a CMS platform like WordPress.
Check the Awesome Self-hosted list on GitHub, has a ton of great stuff.
And in terms of hardware, any old computer or laptop can be used, just install your favorite server OS (Linux, FreeBSD/OpenBSD, even Windows Server). You can play with virtualization too if you have enough horsepower and memory with ESXI or Proxmox, so you can run multiple severs at once on the same computer.
Because these are small shops that have limited availability outside North America, and are fairly expensive compared to Thinkpads which are widely used by corporations, and can be found pretty cheaply.
Meanwhile in Europe, trucks have a flat front so drivers have great visibility.
