What is it now? A sewer of online humans. The ones who can't use any other apps. By big tech, you probably mean mostly Meta, then I agree. I don't see much wrong with Google and Amazon, and even Netflix.

What makes X and Instagram work so well as public boards is that everyone on the planet uses them, so even though it's 90% trash your potential for meeting cool people is basically limitless.
I don't think that will ever be replicated by Nostr or anything else like it.
Messenger apps are different. SimpleX or whatever could easily replace WhatsApp/Discord/Telegram/SMS/whatever else if they had just enough reputation for people to download them, even if it's not totally mainstream.
You don't see much wrong with Google? Weird.
Meta certainly is the worst, but, the rest are nearly as bad.
Humanity is always a gross conglomerate when taken as a whole. Find a pleasant oasis, or, better yet, build one.
I like AOSP and Project Zero. I don't care much about the rest of Google. Had a couple of acquaintances working for them in Mountain View.
Why would I make another clone of twitter or discord? Boring. I'd rather escape into VR or drive all day selling white.
That makes sense.
But... Google is the evil big tech overload OG's younger, better linking brother. (MS is the original evil big tech company, IMO.)
This analogy is breaking my brain. Hard to reason about it cause the hardware changed so much from when MS was relevant.
I like Google as a much lesser evil compared to Apple not MS. I know Google hardware is a joke division in most peoples eyes, but I don't care. AOSP is superior to shit from Canonical or RedHat. Again, can't compare directly, different hardware.
Is modern Microsoft evil? Not at all too. VS code, github, hosting OpenAI.
