An no, there isn't "tons of alternatives". In theory there is. But in practice, they can really make your life harder. Some may say that Signal is an alternative for WhatsApp, but if people you communicate with don't want to use anything but WhatsApp, then Signal is useless. I hate Facebook but when I want to plan an event, I found nothing better, simply because that's the platform that reaches the most people. Network effects... But also, your favorite show may not be on "alternative" streaming platforms, sometimes your job, or worse, the government may require a specific website.

There are extremists who are ready to find alternative friends, shows or jobs just to avoid using some website. It is a good thing these people exist, that's how progress is made. But for most people you have to make compromises.
