These people are documenting the history of an important part of our infrastructure. One video from a channel in this community documented a 1970s home security system as he was contracted to remove it. It’s super fascinating learning how these things function and watching them be tested. Such content can also help a person get over fear of alarms!
This is for content warnings. People discuss political things on a site like blue sky. This is to hide such discussion in case even hearing the topic being discussed is harmful for you. It’s a good feature.
If you have terabytes of data in iCloud, use their mail, contacts, photos, everything? Plus decades of purchased content, expensive devices losing functionality by dropping the iPhone… you have to basically replace everything with something else and it’s tedious especially for a less techy person. This is the reason walled gardens are anti consumer.
I think for most privacy nuts it comes down to “I don’t trust them and it’s closed source. They could be hiding anything in that code.”
And then there’s the people who can’t afford or won’t spend the money it takes to have an enjoyable Apple experience. It genuinely costs multiple thousands of dollars to get into the Apple ecosystem and then it’s massively painful to get out. It’s basically just “corporation bad” because corporations are bad. The only way to be truly private is to not carry a phone at all and use only FOSS solutions.
