I use Microsoft Windows, Apple macOS and Linux. I use GUI and command line. I have quit Twitter and Facebook, although I have dummy accounts there.
I use Telegram, Signal and IRC instead of WhatsApp and Facebook Messenger.
I protect myself from tracking with VPN, AdGuard, Portmaster, hblock, NextDNS and HTTPS filtering. I use ungoogled and libre software as much as I can.
In today's Internet the awareness is the key. You know you're being used and tracked so do something about it. But I myself am not willing to stop using a product just because it's for-profit, has evil corporate behind it. If it's beneficial to me I'm going to exploit the hell out of it in my benefit. I'm not here to make a change, I'm here to live. For now.
Some people just want to see the world burn. I'm something in between.
