What does using a good firewall mean exactly? As I understand it a port is either open or closed right? So what does a good firewall do that a bad one doesn’t?
I’ve bought from aliexpress in the past for obscure electronics that you can’t really get anywhere else for a good price. But I will never shop at temu, I am incredibly suspicious about how they have such an incredibly large advertising budget yet their prices are so low. Either it’s a straight up scam or they are expecting to make a lot of money later down the line
True, but the amount of instances will probably scale too. You can have premium instances that cost a monthly fee, ones that solicit donations, maybe ones that run ads. But you'll also always have the passion project instances being ran for a specific community out of the kindness of someone's heart.
Everything needs to generate some sort of value - I imagine a lemmy instance would generate value for you in the form of learning, or maybe the sense of accomplishment from maintaining a community. That differs from how centralised social media generates value in the form of data or money which is usually at odds with the userbase.
